Sky golem is all profit if you do the smart thing and run old panda farms on multiple toons. Was running 10 farms at one point till bfa launched and was upto my eyeballs in trillium and Ghost iron. Just not been doing it lately, but those 10 farms was an hour a day if that and sustained 4 crafters and alchemists though could have sustained 8 easily.
I got a lucky 350 BoE drop just after hitting 120 about 48 hours after the expansion launched. Was able to sell it for 400k. I had chosen an alt on a different faction as a main this expansion, so I was glad to have more than the 25k I’d previously had. A couple days later I saw another 350 on the AH for 50k and flipped it for 300. That plus farming Monelite Ore as I do World Quest has me sitting on about 1mil.
While the proc is random the law of large numbers will mean that over a large enough sample size your actual yield will be the same as the average proc rate. If you transmute 10 times then you can't rely on the 20% proc rate, once you pass 1000 though, you're average will start approaching the true rate of 1.2 bars per transmute. If you are in this for the long haul it then makes a lot of sense to use the average proc rate to calculate your profits, especially considering the fact that all the items involved sell really well.
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:
When it comes to farming and acquiring stashes of gold, perhaps the first thing that comes to mind is doing raids or dungeons. That sounds great, but there are a few issues. First and foremost, it'd be virtually impossible to solo new content for maximum profit. Then, being in a group means that the earned gold is split and you're only getting a fraction of what you could be getting if you were on your own. Last but not least, finding reliable and good groups for raids and dungeons might prove to be quite the challenge.
Another dungeon farm, this time in Uldum, Tol'Vir trash mobs drop loads of embersilk cloth. Stacks of this tend to sell for a tidy profit, though prices vary depending on the realm. A typical clear of the dungeon takes about 5 minutes, netting about 7.5k per hour in cloth, vendor trash, and various other drops like mats and BoEs. Pick up a Potion of Treasure Finding and farm to your heart's content! It's just as profitable on normal mode as heroic, too, making farming all the quicker and easier.
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.
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.
