Yes, lost at least 5 matches to a 4 melee team the other night - two ret paladins, DK, and rogue, and holy paladin. Both ret paladins bubble at start, dk pops anti-magic shell, rogue uses cloak. Impossible to do any significant amount of magic damage for several seconds. Whole team is dead before bubbles wear off. Holy paladin bubbles if I so much as put a flame shock on her. Don't think I killed anyone on that team.

Another team, caught the feral in stealth with a earthbind totem - instant kill. One trick pony warrior spins around and cuts entire team to 35% hp in a few seconds (20.5k hp 730 resil). Then him and one other dps picked em off easily.
