Need help choosing a class...

[Caridry]

Ok i played a warrior and druid back on classic... both to 60. Me and a friend are starting within a few weeks, and he will be playing a shaman, but we wont always be on together so i need something that can solo semi comfortably.

My choices are, Enchanter (always intrigued me) Monk (i would play this if they can fill in as a temporary tank position?) or warrior (was boring as hell when i played and difficult to level, but it seems the server is hurting for them.)

I know all about the play what you think will be fun, but i dont see looking for groups for hours because of an overpopulus of enchanters, etc. I want to help the server, yet be able to solo well if im looking for a group...
