I have been led to believe that the powertech can do the same type of damage with one pistol as a merc does with 2..then you have the powertech's hield in the other hand which must give it much more defense than the merc..Shouldn't the merc more damage to ompensate for not having a shield...If a powertech can tank and still do comparable damage with it's gun why play a merc besides doing other people the favor of tracer locks or healing?
