Well I'm not really asking what i should do, but more of your opinions and experiences to help me decide. I've Tanked abunch of FPs and i like the survivability in pvp from the tank spec, but I've leveled (and therefor know more about) infiltration and the ability to burst someone down so fast is so appealing.
So yea, all I'm asking for are your opinions. I have enough of a mind to make my own decision.
