Just to throw this out there this is for priests that specced spirit of redemption.
The past few days I've been grouped with retarded tanks, hey it happends. The first pull of the instance the tank took to long to get mobs of me and i died. I said screw it and wasn't going to deal with it and did leave group while in Spirit form then I popped back where I entered the instance from, unscarred.
Simply just leave the group while in spirit form and you will be able to skip the annoying corpse run and possibly the repair bill (ill check that next time).
