I don't see where BRD/MCH is any more difficult or penalized harder than other jobs. They both have a simple priority system of self buffs and other than that it's "what is the most damaging skill can I use now"

Dropping BoD, Enochian, DreadWyrm, Greased, Huton on top of losing your position in a tight rotation is pretty rough.

Yet BRD/MCH pushing every opportunity to inch out their DPS through strict optimisations are very close to melee/mages doing the same with strict rotations.
