State of druids ?

Hello, as we go into the wotlk, I would like to ask you guys, what do you think about Druids. Their viability, usefulness, difficulty etc…I am talking mostly about feral dps, boomie, resto… Do you think that feral/resto is good choice for wotlk content? I am mostly interested into Arenas, but raiding id also pretty fun content for me. Do you think that druid is a good main for wotlk ? Anything other that you would like to share about druids ?THAANKS
