I think what I plan on doing with a single team is leaving them at 84, and turning XP-Off in order to just PvP.

As far as composition, I am thinking I would like to try out a hunter team. And using a Holy Pally as the healer, while using the other two in order to cap them at 84 and run them as a two's team. Grab another Warrior and a healer. Any suggestions?

My current characters account wide:C
Class - Level (Toon #)

Paladin - 85, 60
Deathknight - 85 (4)
Warlock - 64, 60
Shaman - 66, 63 (2)

Looking at gifting 10 toons and then transferring them all.

I have my PvP Team which will remain the 4DK/Pally team.

Going to get a second PvE Team and thinking of:
Death Knight or Warrior Tank (Pro's and Cons)?
Resto Shaman
Warlock
Mage
Mage

PvP Team at 84: Partially twinking

3s Team for BG's (Easier to manage, and less aggro from the public)
Hunter
Hunter
H. Pally

2s Team for giggles and world PvP
Druid
Druid (Both Feral) something I haven't used, maybe dual spec one for a healer. Haven't thought that far yet...

What do you all think?
