Mine was doing arena with 4 mages and a priest (all me) last season. I ran into a bizzare all melee DPS team (probably a 10 game points farming team with 0 rating).

I popped arcane power, icy veins, trinkets and all and cast blizzard x4 between us and mind sear on one and not a single one made it through alive. 10 second victory with 0 damage taken. I wish I had a fraps of that one.
