My friend and i tried this comp and it really works, the downside is, it'll take a while
Warrior(prot)/Pally(prot)
What we did was my pally buddy would throw on his healing gear, but stay in a prot/pvp spec so that he cant be taken down so easily, while throwing out amazing heals.
some of you already probably know this comp, but if you are a prot warrior and/or a prot pally i suggest you try this just for kicks, make sure your pally finds the right spec though. i dont know off the top of my head but if i find out then ill post it
Thx for reading
PS this team is made for outlasting, dont try to kill them like you would if you were dps, but keep pressure on the casters and dont let them drink!
