if you are worried about the xp penalty, then go troll sham (uless barbs have less of a penalty, in that case go with barb) and human monk. xp penalty will be low and you'll kick ass together.

plus when kunark comes out, the monk (if geared up) will be soo pwn

shaman/necro, I don't understand why this combo doesn't get more attention. Yeah yeah shaman/monk seems to be all the rage but coming from someone who played a shaman till 60 don't underestimate the shaman/necro duo.
