i am a lvl 70 shadow priest with almost full t6 armor. i have always played as a shadow priest and so far im liking it. first, shadow priest are very good at dpsing, ive one on oned many rouges(one with 2 warglavies of azzinoth) and beaten most of them. you think shadow priest cant heal, they might not be as good as a holy priest, but they heal very good. i heal about 3500+ with greater heal and mostly crits about 5000. shadow priest have a spell called vampiric embrace which heals party members 25% of the shadow damage you cause to a target for a minute and the cooldown is less than a minute. then vampiric touch which gives 5% of mana to each party member.
