Try doing Darkshore on an undergeared Frost DK when you have no healers and 1 tank. It’s like warfront challenge mode. It was so bad I had to take the little faerie dragon healer thing with the essence buff.
Which by the way that Faerie Dragon is the worst healer ever. The DPS faerie centaur or whatever it is kicks butt but that faerie dragon freakin sucks. Buff it!
