Ah I see so you are still in the gearing up process. Gr 36 isn't terrible from a multibox perspective. Just managing that many characters in GR's is part of the challenge.

Barbs certainly have potential for multiboxing. If I could figure out a spec that could utilize Ground Stomp properly while still doing decent dps I would be all over them, but the way Ground Stomp mechanics work and the amount of CDR needed to get i to work makes it kinda hard to build a dps spec with it.
