What would be good "All Round Team" for a pvp server?

Ofcause it's up to personal preferences, but ill probably start a new team on cataclysm this weekend (friday) and hook up with you guys. If we are able to transfer just 10% of the awesomeness this site got into "our" guild it will be home away from home

I'm considering:

1x priest, 4*mages = Xzin setup = the winz or maybe not anymore but hey they seem fun! No instances though.

5xpaladins? Haven't tried a melee group - but they look awesome. But what happens if they get nerfed next patch or they change the macro function which lets us mb paladins. PvE and PvP

5xshamens - PvP and PvE

1xPriests + 4xWarlocks - PvP and PvE??

Any thoughts about this?

I have a 5xdruid team so if I transfer those or some of them, I would basically get to play any role.
