lol nah, I don't think you've realized this, but unlike pve, pvp is incredibly healing intensive. You don't have time to dps. Heal your team.
You could use your dps abilities in defensive ways that could help your team though;
-If you see an enemy running away from your melee dps? slow their ass down with swiftcast + stella/stone
-You need to get away from annoying enemy dps and/or interupt melee lb? swiftcast + ice 2/holy.
-you wanna interupt enemy bursts at the begining of the match whichnot only helps you but your team too? sprint + swiftcast +holy or sprint + celestial opp
-you want to push some one away from you and sometimes even kill them if you aim it properly? fluid aura
You gotta think outside the box and i know what I'm about to say is going to be taken out of context but in
pvp, you are a healer + support. You are there for that only.
edit - now that i think about it, if for some reason you really wanted to dps as healer, you could just equip int accessories and wear the field commander set and go to town. It would gimp your healing though and people would think you're trolling.
