My list would be: 1. Royal Guard- Best Tank in the game, stun on basic attack. Seems to be a must have going forward to protect any number of other players. 2. Rey- Does the most damage in the game ...
I agree with Doga. My list is similar but would probably take off Lumi and Barriss. Healers are basicaly interchangeable in GW, and still not useful in Arena: the CD reductions may change that.
