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.
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.
It's hard to step out of the shadow of Legion, which was utterly fantastic in almost every way, to enter an expansion where you get one item per boss in the last expansion because the rules have been changed to force more grinding, where you have to grind reputation in the old expansion that you probably skipped because rep grinds suck JUST to unlock allied races (who aren't fully unique races since they recycle old content such as animations), where questing has SOMEHOW become boring again and where your new abilities are given by items you'll swap out every level, meanwhile being only boring passive effects no one cares about.

All are used for some crafts still, and depending on your server you can profit solely by buying mats on the AH, doing your transmute CD, and reposting. Heck many don't even need transmute master to be viable. This can be especially good for those of us who have been playing continuously for years and as a result have alts, many of which that aren't even max level, that we used back then that can still be used.
We push multiple alpha versions to Curse on an average day, these versions may contain important new features or bug fixes for the bleeding edge raid content... These versions are tagged as alpha, so they will not be downloaded by default. Set your Curse client to update to alpha if you want these latest versions (but they may contain bugs, downloads tagged as "Beta" or "Release" are more stable)
There's a few profession crafted pets in BfA on the horizon - Battle for Azeroth Tailoring is getting a Hot Air Balloon style pet, and BfA Alchemy looks to be getting a brand new Transmute Meat to Pet. There are some mount buff consumables from both BfA Leatherworking in the form of a mount barding, and Blacksmithing in Battle for Azeroth will be able to craft Stirrups and Hoofplates to increase mount speed and allow you to interact with things while mounted.
