Condi staff build?
Yes!
I run such kind of build.

Well, staff is kind of a must-have weapon for basically every necro PvP/WvW build, both condi and power based.
Very viable for running around solo or with a few friends, not going to do much in a zerg. You can keep your staff for zerging, but you’ll want to switch to a power build where the staff is mostly just adding aoe filler / pressure.
