Just from a pvp perspective, as a powertech I never get out damaged by a merc. Even as shield spec, not even considering the ridiculous damage that is Pyrotech. Not to mention a powertech can destroy 99% of mercs if he knows what he's doing.
You clearly don't know how to play your own class then go to the forums to complain about it, then when someone says you're wrong you throw a hissy fit and resort to childish insults, nice.
