I leveled 5 Druids till last week
1 Resto + 4 Ferals
DPS was not bad. At 85 with this blue selfmade pvp-gear i did 9000dps.

But it was really annoying in BG to fight against Hunters and Mages. Even with 4x stampeding roar.
You need some range spells or Death Grip. Pure Melee is just frustrating.

Now i playing my DK again. The Tools which Deathknights have is unbelievable good for multiboxing.
