I'm finally home from summer seasonal work, and can devote a lot more time to Warcraft.

I'm the process of leveling (RAF) A-D and C-E, four shaman's, with my already 70 on B for boosting.
I'll also boost hunters, hopefully getting both teams to 70 prior to the expansion.

I'll run 4x Shaman's A/C/D/E as my arena team, with a healer friend.
For BG's, it will be shaman's x5.
My B account has my Pally tank on it, for my PvE group (Pally, Heal-Druid, Mage, Warlock, S.Priest), so she could easily tank something for the four shammies.
I haven't decided yet, if my Warlock or Shaman will be my raiding toon (guild wants one main for raids, but can bring alts for farm content).
Whichever toon is the raider, will level first with the shammies x4, so they're ready to raid asap *and* the shammies can begin the pvp gear up quickly too.
