I was a bit excited once i heard that blizzard has a bigger and newer team handling professions this expansions, but once i started seeing stuff from beta, all of this evaporated pretty quickly.
First thing first -- cooking.
Everyone has already probably heard about Nomi at this point, this food-burning-good-for-nothing-son-of-a-goat.
Cooking worked fine all this time, throughout all expansions, be it's reputation gated recipes or currency gated, doesn't matter.
All those changes simply made cooking more frustrating ( i haven't seen a new recipe for a week already and this is not an exaggeration) and didn't give anything good in return.
Tasty rng, nuff said.
The only good thing about legion cooking is utility food (bear tartares and fighter chow, bacon is useless though).
Next thing is alchemy.
Functionally, nothing has changed.
Yet this rank 3 recipes on flasks and potions kinda fuck over people big time.
Unless you're alchemy/herbing combo, you're excluded from market unless you have a rank 3 recipe.
To get it, you have to make a lot of potions and flasks, and even then, it's not guaranteed.
So you can wasted hundreds if not millions of gold and get jack shit in return.
What was wrong with alchemy in previous expansion when didn't have to deal with rng bullshit ?
Also, utility potions are complete joke.
I don't have herbing, but i've still heard people bitching about getting higher ranks for specific herbs.
Yay for more rng.
Not rng related, but still -- engineering.
I'm a big fan of engineering from the very start of me playing WoW.
I love utility, some quirkiness and overall usefulness of the profession.
Yet this expac, i can name only two items that has some utility -- rezzing pylon and gunpowder charge.
That's it, of all arsenal of legion engineering, we get two semi-useful items.
Just look at other stuff :
Bandage gun -- heal for 100k health, while tanks have > 3 mil health at this point.
Bullet dispenser -- too weak and too expensive.
Auto-hammer -- at this point we have so many ways to repair ourself, that this is simply redundant.
Gunpack -- a gag item, which is not a toy for some reason.
Gunshoes -- 30 secs or so 300 percent movement speed mount, not terribly useful considering it's price and limitations.
Add to this spinal injector that doesn't work in legion (it doesn't scale past WoD) and complete neutering of findle's loot-a-rang.
So, yeah.
