Protip from a Launch Druid: You will rarely root. Ever. At least as a multiboxer, the only time I ever had to root was when I first started out as a boomkin(at 70) and had to hold 'em still while I wrath'd them down; nowadays I just drop a starfire or two and they're dead lol

Pretty much your choice will depend on what you think you need. If you need a tank, go bear, Druids make decent 5man tanks and emergency weak healers if needed.

If your totem micromanagement is good and you can kite well you might consider Boomkin to add the 2 dots in, and maybe focus tank(since we put out FREAKING HUGE threat with our dmg) so your shamen can chain lightning happily :p

I don't recommend resto as a main healer since they rely mostly on HoTs and our only non-hot heal is EFFING SLOW and not as strong as a priest's even when talented lol
