The days that I pvp with my guild for bgs and we already have 2 or 3 healers, normally i'm pvp resto, I'll go boomkin and stay in pve gear with my 2 minute wg 111 sp trinket.
13k SF crits on people when you're hiding are absolutely hilarious. Of course, if people get on me and my melee isnt around to save me the healers usually can't keep me up because I'm like a wet paper towel.
