I've got two teams already, for maximum level play.
5x Feral/Resto's and Paladin + 4x DK's.

The allure of the Paladins...
Quite strong at their level, in relation to other characters... as the game is balanced for maximum level play.
And full gearing that never needs to be upgraded again, with a week of casual pvp or a weekend of lots of pvp.

At the moment they're Holy x5.
But Prot or Ret, or a mixed team is not out.
