Disagree with your comments on Sky Golem. You need about 4200 ghost iron ore make this. Ghost Iron ore turns into bars which are used for Jard's Power source, but you only need 300 bars for that. You also need living steel which is transmuted from triullium, which in turn is transmuted from ghost iron. If you have an transmute master you proc on average about 20 additional trillium bars, that's like 7000g in savings.
Warlocks have received new spell effects; all the other classes received new effects in Legion. Male orcs are now able to toggle between the initial hunched posture and standing upright by using a barbershop, but the other races are not able to toggle between two postures. There are new druid forms for the allied races, i.e. a Zandalari troll forms are all dinosaur-based, while the Kul Tiran humans take forms made of wood and bone as their teachings come from the Drust people who populated the land before them rather than the Cenarion Circle.
If you're willing to dedicate, get tailoring for increased cloth drops, and look at group finder. Under custom search for "boe" and try to find and join a 2x4 farm group. It's basically just hours of leading npcs into a grinder for loot, but you'll make 20-40k an hour from cloth depending on server prices, and on average every 2-4 hrs you'll find a boe epic worth 80-250k, if luck permits.
World of Warcraft’s Legion expansion has been unleashed on the live servers and players are starting to arrive at The Broken Isles to plunder its untouched reserves of gold. Some are diving into the new dungeons and raids while others are undertaking the array of quests in the vast region. See how you, too, can gain immense amounts of gold in this exciting expansion.
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.
I'm pretty excited about where the various gathering professions could go this expansion. Crafting expansions actually have good stuff to craft to prepare for the upcoming raid so gathering items will be needed. On top of that nodes are giving out less so more effort equals higher prices. Now where this goes past launch I'm not sure but stuff like Mining and Herbalism should be solid at the beginning.
They'll still be able to craft their items. Xmog crafters won't feel as hit because most of those patterns aren't terribly easy to come by. Mount sellers won't be affected. Recipes wont really be affected. Trade Goods will change a bit though, but that isn't inherently a bad thing. I can never find Firebloom on my server for sale, Mageweave and Silk are always pricey, etc. It might increase the amounts of those types of items and drive the price down, but that might be replaced by something else just as easily.
Thing is, as in real life, opportunity cost is the real key on this. I'm getting 2 tokens per month quite easily with just 3 toons (1 maxed only (yeah, pretty damn inefficient but I lack a lot of time to play :p)) just by flipping couple of things, food, flask, potions, bags, shirts (yeah, shirts!!), etc etc. Every damn penny/gold counts :p, just have to learn how your realm market works, what niches exist, which items are needed and undersupplied and which are oversupplied.
My second most anticipated new feature in the Tides of Vengeance update is the Battle for Darkshore Warfront. It’s the second cyclical battle between the Horde and Alliance, in which each faction takes turns gathering resources, fighting in a pitched raid battle and then controlling the Darkshore zone. In what I hope will be an improvement to the Warfronts feature, the controlling faction will gain access to diverse world quests in the zones they control, rather than the “kill x of y” quests from when it first launched.
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.
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.

Crafting (Blacksmithing, Tailoring, Leatherworking) – When it comes to endgame, I always found crafting to be very dependent on the level of gear you can produce. There have been times when the crafted gear was competitive with the gear you could get in the open world and during those times I always had success. Then there are the dead times when the game gear vastly out levels anything you can craft. There still is time before BfA launch for the devs to make more changes, so I am not sure where crafting is going to come out this time. Whatever they do, I have always made some gold selling transmog and Blacksmithing has shined in this area for me. Many folks don’t take the time to collect old rare recipes which can leave few competitors. Transmog never sells fast, but it can work.
At least they didn't require dungeons and raids to get through the basic skilling-up this time; I remember a lot of people were unhappy about that in Legion; I boosted some through for quests who weren't comfortable in a queue. It was always a traditional occupation for people who don't/can't group. Again, I appreciate the small mercy. They may need to strangle professions, but it was unnecessary to be just mean to people.
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. Characters with War Mode activated are only able to see other players with War Mode, unless in their own capital cities.
