Would 2 rogues possibly work in Arena? Sap and double ambush? Shadow Step to reposition? xD
I like to think rogues would have a lot more control and flow of fights if you get the opener. But this could all be a meme in my head with the difficulties of pulling off a melee group
The burst of two hunters could be nice, and kind of nice to only worry about doing DPS instead of trying to juggle a a hybrid and 1 dps.
