So My char's hit 58 today, but I can't go into outlands yet cus I'm buying TBC tomorrow. So I got a question meanwhile.

My setup is a 70 warlock and 4xdruids. Until now I have always used the warlock as my main and kinda powerleveled the druids. But my guess is that neither the lock or the voidwalker will be able to tank in ramparts and up. So I'm wondering if I should make on of the druids feral and use him as my main and for tanking. What do you guys think?
And btw, do you guys use on alt as a main healer, or letting all of them heal/dps?

If you got some spare time write how you manage all of this and what problems I might be facing.
