Two completely different play styles, I realize that... I understand I need to pick what I am best at.

Through BC and WOTLK I always played as a resto druid. As I really enjoyed doing this, towards the end of the WOTLK I became bored with it and started dabbling around in the feral and boomkin trees. With that being said, I know I want to be a dps in pvp for cata. At this time I do not know a lot about either in PvP and was looking for peoples opinions on these classes. What are there strong suits? What is more viable in arena? What is looking to be the more dominant class in battlegrounds? I feel like they both have a lot to offer and i expect to try out both specs to see which I like best. Which should I try first and why? Please dont say one or the other cuz its OP right now because thats going to change (feral bleeds just got fixed!). Any information would be helpful.

Thanks
