Chemistry needs some changes.

Dude, get a grip. Me, isaac, damian and dave were doing chemmurder by the heaps while you were still toying with napalm.
There even used to be two ways to explode azide on command, but then some changes happened, and they couldn't be performed.
Fetchquest doesn't mean going to hydro to get X, it means bothering with telesci to get spider eggs.

Initro, serum and all the super complex recipes add nothing to chemistry. They are a fun puzzle, but solving incredibly hard recipes is not what I like about chemistry (in fact, the new medicines are a step in the right direction).
Chemistry should become more flexible, have less hard recipes and more mechanics.
