World of warcraft - Rogue, Hunter, Druid, Pally, Warlock or Shaman for PvE Dps?

I dunno which one to go, i like the druid and the pally because i can tank until level 85 but then in raids ill do dps because im bad at raid tanking. Which one would do best dps at 85 and stuff? Is Feral/Balance druid good? Pally dps is that good?
