I have been playing since 2005. I have never really relied on the auction house to make my gold (I don't have the time, what with me having a life and all). In fact, I hardly ever use it. But as the years went by, I've always managed to get my gold total to progressively increase with each expansion. Not so with BFA. In fact, my total has actually gone down since BFA launch. Is this normal? Yes, I have been buying items from the rep guys, but I do that with every expansion. My gold started stagnating a bit before BFA, but since launch ... wow! I guess I can kiss that dinosaur mount goodbye!
"Players can get these powerful items, empower them, and which gameplay-affecting powers they want to use or focus on without feeling like they’re just playing the lottery and hoping they get the Pyroblast Bracers or whatever the magical legendary they need to enable the rotation they want to do," Hazzikostas said. "Instead, they can just look at the dungeon journal, look at raid bosses, see where the azurite armor with the powers they want comes from, and focus on getting that and leveling their artifact naturally, in a much more controlled way."

I don't think that made professions all that useful. And it was a huge burden to the fun of getting new gear. I like that if I get a new piece of gear in a raid I can generally equip it right away. Couldn't do that when half the gear you get need enchants/gems/whatever. Why not just bring back re-forging then? Though I did like upgrading gear when that was a thing.

PLUNDER THE ISLANDS OF THE GREAT SEA – Explore Azeroth’s uncharted isles in Island Expeditions. Battle in groups of three as you race against cunning rival intruders (or enemy players) to collect the island’s resources and fuel the war effort. Constantly evolving challenges await as you traverse frozen landscapes near Northrend, open the gates of an abandoned Gilnean castle, navigate a war between elementals, and more.
Strictly speaking, reselling items is not making gold. At best, you are "making gold" for yourself. There has been huge deflation with BfA launch (check token value lol) and personally I really want to see how Blizzard "economy" team is going to react, because effects of deflation are ranging from bad to terrible. No idea what is this experiment about?

Those are low prices indeed! In those cases, just look into something else, but there's always gold to be made, as you pointed out :) And there is no shame in being unefficient, not everyone wants to spend their time getting optimized for goldmaking, if you can pay for your month I think it's great already! That's what kept me into it, the fact that I'm paying by playing, I love it
2. Island Expeditions. What?! you may ask, but it is simple. The transmog that drops, now rather frequently, from the expeditions sells well and for high amounts. Despite its somewhat common drop rate the fact that the loot table is so large means that people seeking certain transmog will be more likely to buy it than farm it. The parroted meme on r/wow that it is unrewarding only makes it better for someone like me. In the past two days from doing Island Expeditions on the side (about 20 total) I got 6 transmog items of TSM values between 15k and 150k. I sold 3 so far totaling 140k (Plundered Squid Caster: 50k because I wanted to be rid of it, Stinkrot Smasher: 69k, Razorfin Breastplate: 28k). Pet drops are a different story and while you can sell them, the fact that they need to be looted for the achievement means that the potential buyer pool is smaller.
This expansion suffers from the Warlords of Draenor (WoD) effect, initially, players will think this is a great expansion but upon investing some time into the game they'll realize this game is a disaster. The pre-patch should have been our first warning with how poorly designed and executed that fiasco was, but beyond that, let's look at what the expansion itself offers:
The thing I liked best about the wide shuffle of those days was that it made ALL of my alts feel valuable. I'd get some ore some was sent to the miner to be smelted and then on to the blacksmith for belt buckles. The rest went to the jewelcrafter to prospect. Some of those got cut, the rest got turned into jewelry that was either sold or disenchanted. The enchanter then converted those mats into scrolls. Meanwhile the army of alchemists transmuted that expansion's elemental material (volatiles, sorcerous, etc). It felt like a whole business operation.

What’s worse, it’s rarely satisfying when you do make it to a new milestone in your grind to unlock the gear you need. Legion had legendary items that changed the way an ability functioned, which would also completely change the way classes played; the Azerite traits in the Battle for Azeroth are rarely as interesting. Instead, they are simply passive bonuses that, in most cases, help you do more damage without any extra effort on your part. While some classes are lucky enough to have traits that change their gameplay slightly, Blizzard has so far seemed to favor nerfing those traits out of viability for most specs.
This gold making advice is applicable to most players, except if you are an enchanter, in which case there is a very strong case to turn them into dust and essence for your profession needs. As an advanced tip, you can explore the use of mobile apps that let you post on the auction house at the right time because the price of greens tends to fluctuate rapidly, and could mean a large loss of potential gold income.

Professions have changed dramatically in Legion. While before you simply had to pay for recipes when you were in town, now the trainers as you to gather certain materials or defeat certain targets in order to unlock additional recipes. How can you profit from this new system? Well, to compensate players with the harder recipe unlocks, the developers have implemented a recipe rank system.

Professions are skills used to create and enhance items (gears). You will start with one skill once your character has learned a profession. When you use the profession, your skill will increase. A profession’s higher skill will allow you to create more powerful items. If you change a primary profession, you will lose any skill you have made with your original profession. So it is important to choose your primary professions wisely.

 Kul Tiran human (8.1.5) - "Kul Tiras was founded by fearless explorers who sailed uncharted waters in search of adventure. As a key member of the Alliance of Lordaeron, the Kul Tiran navy dominated the seas of Azeroth with its legendary fleet. But after years of turmoil and hardship, the kingdom grew isolated and vulnerable to dark influences. Thanks to the help of brave heroes, House Proudmoore has been restored and Kul Tiras is poised to fight alongside the valiant Alliance once more."

Professions skills are split between expansions now, you'll have a separate skill bar for each expansion. This means you can level the new Battle for Azeroth skill tier without putting any point into any of the previous expansions tiers, you don't have to level Leatherworking with older materials to be able to craft the new BfA items. You can read more about this in my BfA Profession overview.

A: The WoW Token feature is designed to facilitate the exchange of gold and game time between players in as secure, convenient, and fair a way as possible, and without making players feel like they’re playing a game with their hard-earned money. Having a set current market price and a straightforward exchange system is the best way to achieve that—you don’t need to worry about whether your Token will sell or not due to being undercut or the market shifting, and everyone receives exactly the amount of gold they were quoted.
With the most in-demand decks going for up to 20,000 Gold each, Basil believes that Darkmoon cards (12 of which when combined form a full deck) can earn scribes the highest possible WoW Gold. But he said that it takes intricate planning and logistics to really ramp up the Gold income from Darkmoon cards due to the constraints surrounding its crafting cooldown.
