I'm, not very good and don't think snipers (which I play) are particularly powerful.
But as a noob 50 I get gang F***** every time I wander too close the fray.
What that tells me is that the enemy team wants me dead fast regardless of my noobitude.
They go out of their way to kill me quickly. I don't feel like much of a threat (especially since my gear is not good PvP gear yet). But obviously it seems like a standard tactic to down the sniper first and fast.
I am new to 50 PvP and am usually the only sniper or one of two snipers (rare) in a WZ.
So I don't really know the verdict is still out for me...though I won't swear off buffs .
I get my *** kicked but still get medals and comms..so I don't leave empty handed.
On another note I think Alderaan is the most sniper friendly map....unless other snipers want to share some tactics with me on huttball and void.
