Clash mode, a 3v3 pvp concept.

So this is not an original concept, but a mode that i think could possibly work in wow. The two main games that i know it from would be the original, Marvel vs capcom, and a mmo that did it, Blade and soul. In this mode, you are placed on a team of 3 people, and each team starts off with 1 player in the arena chosen at random, while the other 2 wait in the wings. The mode essentially plays out like 3 back to back 1v1's with the ability to swap out for another of your teammates on a cooldown. You fight until all opponents are dead on one team.
