Recommended Class Combo / EXP Gain?

I'm looking to 3 / 4 Box. I am going to be using 1 PC, eVGA 680i LT / e6600 OC'd to 3.4GHz / 4GB RAM / 9800GX2 OC'd. Anyway, I want to be doing PvP if I ever get them high enough to do so. Are Shamans the way to go or would druids be a better bet?

Also, when all of my characters are grouped, they don't get much XP per kill, obviously. How do you guys, the experts, level mostly? Through quests? Any feedback would be appreciated greatly!

search the forums and you will find answers to all these questions, you will also find more useful information, just by search and reading posts on how to become a better boxer and you will progress alot faster.

Almost everyone does shamans, for good reasons.

I would roll druids. Everyone doer shamans for a reason but they arent the only good class.
