im playing a gunslinger and was having trouble killing them. They killed my tank pet in seconds i barely got them down to half health.

I've just got off the space ship to Alderaan and i started doing this quest chain Paladins... Im on the part were you are asked to fight and kill 3 sith app and no matter what type i choose im getting owned in seconds by either one( inq or warrior) are these bugged or should these be labeled as Group quest...either way im getting owned and it shouldnt be that dang hard.
