fire/kin
It does lots of half jobs, but has no real clear strength
Actually, since you mentioned debuffs and Imps, I recommend Fire/Rad for you then.
Kin won't debuff your opponent's protection. With Rad, you can debuff and let the Imps do the damage.
I've already tried to use Power Sink from my Brute the same way you suggested. Against a good player, it will help but won't leave them without any Endurance. Against melee oponents, it is very useful.
I am just totally wondering, what is fire/kinetics actually like in pvp?
I suppose you could spam transferance to drain there end and for the +self recovery
and maybe you could spam some other debuffs then let your holds and imps do the stuff
Is It Good Though? Or would any scrapper or blaster just beat them silly?
