Ugh...and I want some cake =P

Anyway, personally I have two teams. I have a 5x draenei shaman team for PVP and a Warlock/Priest/Mage/Druid/Paladin team for PVE. Both teams are on different PVP servers and like you, I've never been on one. I'm hoping people don't mess with me too much b/c I'm not sure how well I'd do with the PVE team. On the shaman team, I want people to attack me all the time b/c I've read here what they can do

I completely agree with you about not wanting the same classes in both teams. My main reason also for doing the complicated 5-class team was b/c at 70 if I want to run solo content I would have a wide variety of toons to choose from. I do know that having two teams will take a bit longer to level and gear but I'm ready for the challenge.

Since you're leaning towards 1 team, I'd start with your druid, 4x shaman team. That team would do great in PVE (I can imagine) and for PVP you can always just take the four shaman into the battlegrounds (if you can't handle having the druid there). If you've watched any of the videos here about the shaman crews, you can see how much they destroy people. Then once you get to 62ish you can swap out your druid for the pally. As far as I've read, pallies are the best tanks for multiboxers (AoE tanking ftw!) so you'll probably want him/her in the heroics.

Hope that helps and whatever you choose, good luck leveling!
