I'm interested to see if they can replace Paladins as the de facto tanks for multiboxing as it seems to me that they're going to be bringing *a lot* to arenas. Their "zomg 6 seconds heals turn to damage shields turn to damage KAPLOW" ability is just plain crazy. For that reason alone I think they'll edge out other non-pure damage dealers. I guess we'll see.

Edit: I'm saying I'd like to see if they replace them as a tank so I can go 1x DK 4x Shaman to get to 80, as it were
