Sounds boring and lame. Who wants to play a game where everyone can do the exact same things.
This would solve the problems with:

MP- Mochums buffs
MA- Crit buff

The reason im posting this here is a thread started by an engi in the traders forum about how Engi. should be better at trade skill than traders.
I think my answer, solves all the problems.
