This comp would be good because the crowd control, the damage from the barbs burst/witch doctors spreading dots. with the monk helping the damage with his spirit generator. Wall of Zombies + Inner Sanctuary would make opposing monks and barbs hard to sit on the monk or witch doctor. they're only target would be barb. which lets the monk be able to heal and the witch doctor to crowd control. This is more of a Anti-melee but the barb is very mobile and will be able to squash wizards.
