50. Dirty Fighter Gunslinger here.
I'm pretty sure there's a "my class is broken" topic on every class. But seriously, we get off pretty well. I can generally top the damage and kills of the PvP charts and have consistent one-on-one victories with pretty much every class. More importantly, in group situations, I can do further damage, quite frankly because a lot of people dismiss blaster fire as non-threatening---that is compared to visually overwhelming lightning, waving lightsabers, and GIANT FLYING DEBRIS.
1. Yes, as a DF/Lethality, a healer's cleanse spell somewhat dilutes your effectiveness. That's why: a) you have teammates b) you can EASILY kill the healer with burst damage c) You have 3 whole interrupts/stuns at your disposal.....and finally d) you use your DoTs tax the healer's attention and resources. Tagging all enemy players you see with even 1 DoT = hilarity ensues.
2. As a DF/Lethality, you can kite like no other. Again, you have 2 stuns + 1 snare at your disposal---not to mention slow effects of DF/Lethality
3. Your AoE output + cybertech grenades are amazing. Whether it's a variation of XS Freighter Flyby, a gas/shrap grenade, thermal detonator, and all manner of high damage AoE, you rock this.
Does it help that I'm decked out in all endgame gear? Probably. Does it help that everyone dismisses sniper/slinger as no threat? Also probably true. Hmmm, perhaps we should keep it that way for our benefit...
