Concoctor's Clutch (Alchemy profession bag) is useless

[Lethora-shadowsong]

I already learned all recipes from experimentation without the bag, so what’s the point of making the bag now? Every other profession has at least some kind of minor useful bonus while alchemy gets none.
This bag need to be changed and provide some kind of bonus that would work for the rest of expansion and not just first two weeks.
