Hey guys, BZM 'the n00b multiboxer' here!

Been multiboxing for like 3 days and love it.

Currently I've learned that casters and ranged are great for boxing. Also paladin tanks are OP!

So as I'm building my groups and skills up to running an actual mixed 5 man team, I have the following plans:

For sure will level:
Healers / Ranged DPS - shamans, hunters, druids, priests, mages, warlocks
Tanks / Melee - paladins, DKs, monks

This sort of leaves Warriors and Rogues out. Is there any reason to build a group of these classes?
