The older brother of this potion originally came about in Cataclysm as the Potion of Treasure Finding, and is actually one of the best ways to make money. Since most Pandaria mats are constantly farmed, they usually sell for less than the Cataclysm mats. This makes using this form of the potion more effective for making gold. Not to mention that creatures die faster to level 90s since they were made for the previous expansion, making farming the treasure chests that drop rather easy.
Hazzikostas posted the changes in a new blog post on the official WoW forums. Season 2 will go live on January 22 with new Warfronts, Mythic + PvP, World Content, a new Titanforging cap and much more. We’ve included his post down below and have also included a follow up post about rewarding loot for Emissaries and Assault quests based on loot specialization.

Yes, that is easy, but it's not quick. Further down in my comments to OP I detailed the GIO farm, and reasonable yield expectations. I looked up a few guides/videos before commenting and most of them estimate a yield beween 800-1,000 GIO/hour. That lines up with my past experience with it as well. That'd be, taking the high yield end, 4.2 hours to farm the GIO for one toon's monthly needs.
I'm aware that the LS chain can be xmuted up all the way up from GIO. This is great since it means ultimately you only need to track/acquire one item. The procs can certainly increase your profit margin, but as I said in my top-level comment the profitability of the whole endeavor is server-dependent. These numbers will of course vary from server to server, and for some it might be worth it.
The expansion brings a major change to the PvP ruleset on each realm. Every realm by default only allows players to attack NPCs in the open world; players who wish to engage in world PvP now have a setting called "War Mode" that can only be toggled on or off in their faction's capital city (i.e. Stormwind for the Alliance and Orgrimmar for the Horde). While in War Mode, players have access to new talents and abilities, as well as a slightly accelerated rate of XP gain.[10] Characters with War Mode activated are only able to see other players with War Mode, unless in their own capital cities.
"Essentially the Scrap-o-Matic 1000 (and Shred-Master Mk1) works like the Obliterum Forge in Legion however one major difference from Legion is that you can use it to break down any gear obtained that is from the Battle for Azeroth expansion, including dungeon/raid drops, quest rewards, world drops and crafted gear. Apart from a chance at getting Expulsion you will also get ore, gems, leather, occasional enchanting mats (from scrapping cloth gear) and other crafting mats. The best way to obtain Expulsion seems to be from breaking down rare/epic gear you obtain from dungeons and raids, killing rare elites and doing world quests, it also drops rarely from BFA uncommon quality items."
Edit: Emphasized AGAIN here and there that these were examples because apparently nobody reads the whole thing before talking about how this is a guide or that these markets/farms specifically require effort etc... No one should just read about examples and think "Okay I'll do it". You should just see if it works, if it does you CAN do it, else you find something ELSE.
I know if you aren't using hunters than you'll really want the loot-a-rang for easy looting, so that would take up one of your professions. In all honesty If i was going to do it id level up a hunter team and only hyperfarm with them, while doing other things with the mains. As far as regular professions go, they don't really seem worth it anymore like they did back in the old days, so I'd personally stick with gathering stuff as you are hitting nodes x5
I think that's server dependant. I make a lot of Golems, but the price on my server is high enough that you could buy all the living steel and still make about 20K (almost 200kg on AH). Its just that you proc all the way up the chain. You proc 20% of your trillium, and then 20% of your living steel. SoH and Ghost Iron are such low effort farms, too. 20% of 180 Trillium Bars at 500g is 18k more profit, 20% of 150 Living Steel at 3500g is another 105kg. That's an extra 25k profit per Golem. If they stop selling stockpile them for the next expansion, they always boom with the price of herbs. And a consistent 20% proc rate is the opposite of RNG, its extra free stuff as a benefit to completing an extra quest (not to mention for new alchemists the investment of leveling Vanilla Alchemy). You're looking for some get rich quick scheme, where the real way to build wealth is patience and volume. No market is going to be viable because you want it to be. Only because you make it viable.

Charge Into the Warfronts: Fight on the battlefields of a large-scale, 20-player cooperative Warfront to claim a key strategic location. Capture resources to build your faction’s forces, lead the charge as your troops lay siege to objectives, and fight the enemy commander to claim victory in this new PvE mode inspired by classic Warcraft RTS battles.
Mythic+ has some similarity to raiding, but it’s designed for just five players, instead of the 10-to-30 that can make up a raid. This mode tasks players with clearing the game’s dungeons, but with specific changes that make them harder, scaling up until it’s impossible for groups to finish. Players receive a keystone in their inventory that assigns them their dungeon, one of the game’s 10, and gives the dungeon a level. This determines how difficult enemies are and what effects might make them harder. If the group completes the keystone in time, they get a new, higher-level stone; if they, don’t they get a lower-level stone.
With G'huun's threat eliminated, the Horde and Alliance return their focus to the war. While the Horde procures the Scepter of the Tides, a legendary artifact capable of controlling the seas, the Alliance dismantles a potential alliance between Sylvanas and the vampiric San'lyan Elves. The Alliance begins to gear up for a preemptive strike against Zandalar, with the goal of crippling the Golden Fleet before it can be used against the Alliance and driving a wedge between the Zandalari and the Horde.

A new expansion unlocks exponentially more powerful gear, letting you easily breeze through Warlords of Draenor dungeons and raids. A great gold making strategy is to solo these challenges and amass a large amount of gold that you get to keep instead of splitting with your group. Start with soloing easy dungeons and work your way towards harder dungeons until you are comfortable enough to take on soloing raids. Speed and clearing ability is key – stick to those you can run through without skipping a beat and you will see your gold making per hour go through the roof.

That's mostly it, but it's linked to the fact you can transmute ghost iron bars into trillium bars, which can be transmuted into Living Steel. So ghost iron is really really useful for sky golems and panther mounts, because they require 4 Living Steel's, which means 24 trilliums or 240 Ghost Iron bars, if you wanna go that way instead of farming the trillium itself!
Making gold = work, people just want to be lazy and cash in but today a lot of people use TSM, have access to this reddit, youtube guides, etc. More and more people play wow to make gold so ofc the AH work gets harder, you just need to find your niche, i'm making gold with Tailoring from MoP and Cata for transmogs, not a lot of work to farm maths and i sell each piece around 10k, 7 pieces per week and i'm fine for a month.
Today's events set the stage for major changes in the game, including the expansion pre-patch, which will include all the game systems, cosmetic and other changes for the new expansion - basically, everything but the content in the expansion's new zones. There has been no official announcement of the prepatch launch date, but if I were a betting woman, I'd say July 10 looks awfully likely. [Edit: All right, or the 17th. But plan for the worst, people.]
As the battle for Darkshore begins, both the Alliance and Horde are blindsided by a new development: High Overlord Saurfang, who had been defeated and captured in the Battle of Lordearon, has suddenly escaped Alliance captivity and is on the run. Sylvanas sends Horde Champions to track Saurfang down, ostensibly to extract him. However, it quickly becomes apparent that the search party is in fact an assassination squad, as Sylvanas suspects Saurfang of colluding with the Alliance in an attempt to dethrone her. While some Horde champions choose to side with Saurfang and help him escape the assassins, other champions remain loyal to Sylvanas and report Saurfang's and the dissenting champions' treachery to her.
I'm holding a huge stock of herbs, flasks, pots, gems, fish, feasts/foods to sell when Uldir releases. Its already too close to start investing into that so I would just farm herbs and try to sell Anchor Weed as fast as possible right now when price is still high. Blizz can buff spawn rate anytime or reduce materials needed like they did with feasts.
Azeroth paid a terrible price to end the apocalyptic march of the Legion’s crusade—but even as the world’s wounds are tended, it is the shattered trust between the Alliance and Horde that may prove hardest to mend. As this age-old conflict reignites, gather your allies and champion your faction’s cause—for Azeroth’s future will be forged in the fires of war.
Tbh high prices of enchants / gems / flasks / augment runes / food buffs are mostly an opportunity for casuals to make gold. Majority of them don't use these for themselves. How often do you do casual content and see casual players use flasks, gem and enchant their gear? I rarely do. It's common to pug a normal raid or similar content and see people ungemmed / unenchanted and using no consumables unless someone drops down a feast. It's simply not necessary and not required in casual content and people don't bother. Not even mentioning more casual levels like lfr and open world content.
Set up TSM properly, learn it well and I can already see the power potential it has. Second is diversify your markets, learn other markets and the more you set up the more potential profit you have. Third is probably leveling alts so you have a wide range of professions ready to tackle any future opportunities for profit. Forth read patch notes religiously.
Allied races aren’t much better. You can only earn them by grinding out reputation. It doesn’t take that long but casual players will need to invest a couple weeks primarily to it, and focusing on that grind will take you away from others, like earning gear. Each race has its own grind, but the things you do to work through it remain the same, adding to your boredom.
