Why are you saying this would cut your margins down? If anything, it would increase your margins because all those scrapper mats are gonna be sold on the AH driving down the price, so each item is less expensive for you to craft, so your margins get bigger if keeping the same sale price. So long term this would probably drive down your sale price just due to supply and demand, so you would have to sell more to keep the same income, however that’s unrelated to your margins.
It's not about me, it's about people having trouble making gold with BfA professions for example, or having herb prices drop too low to make it worth the effort, I just meant to say there are other ways of making gold. I personnally make most my gold out of BfA for example, so I wanted to point out it's not a necessary thing to stick to the current extension.
The last thing I want to say about this farm, you definitely need aoe damage dealers and some ranged people because mobs are not actually too close each other. So, you need to run around and gather mobs in one place with a monk statue and kill them with aoe. The party setups are simple and same with other farms actually and I don’t think not need to talk more about it.
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.
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.
-Bugs- There aren't too many glaring bugs anymore, but you will certainly encounter some. The pathetic thing is that many of the bugs you'll encounter were reported repeatedly during Alpha/Beta and still weren't fixed. Some bugs were discovered after release and players were able to abuse game mechanics without repercussion unless they were one of the more serious offenders. This gave some players a significant advantage over others because they used exploits and at the start of an expansion, that is the time when it's most impactful.
When were professions really good, in your opinion? I remember having fun with them in Cata, but that was because I was playing the gold-making minigame of grinding the ore -> gem -> j/c boe's -> d/e mats cycle, back when gemming/enchanting your gear seemed absolutely necessary and people not in accordance with Mr. Robot were kicked from groups. Oh yeah, and don't forget the primary stat boost for BoP gear that was profession-specific that made gathering professions anathema to a raiding toon.
The Heart of Azeroth is an artifact given to the player character from the world soul via Magni Bronzebeard. It is a necklace that can use the power of Azerite, the lifeblood of the embryonic titan Azeroth (See Plot, below). Azerite is similar in function to Legion's artifact power, in that it is gathered normally from playing the game and is used to upgrade an artifact; likewise, the Heart is similar in function to Legion's artifact weapons by having the capacity to be constantly upgraded. Unlike artifact weapons, however, the Heart is shared with all of the player's specializations and can empower all eligible pieces worn simultaneously.
"Essentially the Scrap-o-Matic 1000 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 Expulsom you will also get ore, gems, leather, occasional enchanting mats (from scrapping cloth gear) and other crafting mats. The best way to obtain Expulsom 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."

That's where i'm at now. I got into it late. I had 40k to start. Sold fish up to about 100k total starting capital. Started making and selling decks when they were going for 80-200k on my server. Morons have repeatedly undercut decks by 30-60k at a time even after the market has been reset (not by me) multiple times. Now the decks are 25-80k... I did manage to make 3.5m gross in the last 2 weeks. Now the individual cards are selling for MUCH less than the decks so I may stop crafting myself and just start buying the individuals... idk where to go from there though. Do you think the decks will hold any value moving forward? I'm kind of hoping for something similar to obliterum in legion to increase the ilvl and keep them relevant.
