Why? Snipers have small magazine sizes so you can't get full use of phase lock and skills supporting it with a sniper. In the time in which you could've emptied a SMG mag on a phaselocked enemy with wreck, you wouldn't get too many sniper shots in because of slow fire rate and reload. Besides, if you want to inflict elemental damage you could just invest in chain reaction and wreck and have elemental bullets flying everywhere when shooting a phaselocked enemy with a vladof pistol or a SMG.

hm..so what build do u recommend? ;o

I dont remember my build exactly to the point but max atleast: ward, wreck, reaper, helios, chain reaction, that magazine size increasing skill and invest a point or two in that life orb thingy. My build focuses on phaselocking a (strong) enemy and pouring a magazine on it, harming other enemies as well. But you can always try different builds to find one you like.

And this did a lot of damage?

Worked for me
