I see what i can do for you guys. (I have not tried the WD so that one might need a bit of work, however I will do my best. )
Wizard Spec: http://eu.battle.net/d3/en/calculator/wizard#acROSm!YXg!bbbYZc
Witch Docter: http://eu.battle.net/d3/en/calculator/witch-doctor#aZUdkQ!hbW!aacYab
My thoughts choosing these specs:
Wizard will be the damage dealer, and the Witch Docter the buff and Crowd Control.
I do not know anything about the Witch Docter so I gave it my best shot.
Thanks for the suggestions - it is hard to know what will translate well from theory until it has been tried, I like your use of WD though - just highlighted to me how focused he's been on dps as opposed to some good cc options. Just one thing about the wiz build though - Why critical mass? It seems a bit of a waste to use up a whole passive for one skill (archon)?
