I'd like to add my personal experience as of a week ago in regards to illusions: I bought all of them for 10 silver being the highest bidder. They sell for 2-4k each usually, but it's a very slow market with little interest. They might be a nice addition to your portfolio if you can get the mats with little effort, otherwise it's not enough to warrant investing in it. At least on my server.
But the system offers a painful and mindless grind. At worst, it feels like a cheap and artificial wall blocking you from playing your character to its full potential. Levels of your heart come fast at first, but the costs become prohibitive when you get up into level 20 or so. This wouldn’t be an issue if the most powerful Azerite gear didn’t require reaching level 22 to unlock even 75 percent of their full damage, leaving players left out of features from gear they’ve already collected. This means more grinding.

-Gameplay- Gameplay has largely been stripped down to be a shell of its former self. This trimming has been going on for several expansions, but now it's even worse. Classes only have so many buttons which has resulted in very little skill involved in PvE (even PvP is a faceroll for most melee, lacking any sort of depth and decision-making as it's pretty clear what buttons to press in any given situation) and it's become more of a gear check. This expansion gave zero new abilities to classes, only took them away.
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.

In a few months only mats will be worth anything. At this point we have people with tens of millions of gold and people with just a few thousands. A flask takes tons of mats to make, and they will sell for well over 10k gold each, so the casual players won't afford them. When people realize that the rich guys will always take buying from the AH over farming their own mats, the prices will go even higher, then casuals will notice how expensive flasks are, and they will pick up alchemy and make more flasks, driving the prices down again.
