Only if u straight add up every debuff it will be a 150% or so, but its more like 100%. Remember several debuffs are additive and u can't just add them like that. Still, the logic is the same. 1 WD will add same or even more DPS than 1 wizard but a ton more survivability. Try a simulation in d3planner and u will see how it can double a wizard's dps. Crazy :P
