3x boxin Wow - Which Team?

Hey gang...fairly new to MB, got 3 accounts, 1PC and Keyclone up and running.

Thinking of one of the following teams, on a PVP server:

1War, 2 Ele Shammies

1 Prot Pally, 2 Mages

1 Prot Pally, 2 Demo Locks

1 Prot Pally, 2 Ele Shammies


Thoughts? Suggestions? Also, if mages, is Arcane viable for leveling? Arcane missiles and AE x 2 sounds sekc. :)

Thanks!!
