Just hit lvl 80 with my undead priest...Currently I am dual spec in Shadow/Holy...Would like to do more pvp - however I've had mixed results (get stunned easily - although I do not have extra points in psychic scream) while in shadow form, and was wondering if I'd have better luck if I re-specced to Disc?...My #1 concern with Disc is that I'd lose my dps abilities that I've grown fond of while in shadow form.

I'd like to continue healing in dungeons, and would probably keep my Holy spec as is since I've had great success in that format.

Any suggestions as to how I could potentially improve my pvp abilities - I'd greatly appreciate it!
