An interesting idea but Nazeem just doesn't have the damage to be a dps or the healing to be a healer and whilst being a good source of curse, it does not make up for 50% dmg on his base attacks. He may be improved at some point, but if there is another option available, its probably better than Nazeem. There is however one place Nazeem gets to shine. If built with high attack speed, he can consistently stun all saw phases in Guild boss 2.
