It's gonna be nerfed after S5 for sure. It's utterly broken. The problem is the sword, not the class, the set or the skills at all. The supports are there to increase toughness, provide endless amount of arcane power and IAS. It's all about IAS. The more speed, the more twisters u can have in 6 secs and the sword will increase your damage 150% per twister. If there are no AP issues and u have insane APS (also around 100%+ Area Damage), then your damage will scale like crazy. That's why they use Pain Enhancer (rank 25 is enough cause they only care about the IAS effect of the gem) and focus on high density. With a huge amount of mobs, u will prolly hit the highest breakpoint and have like 30 twisters stacking the 150% damage increase from the sword.
This post explains it pretty good:

No other class comes even remotely close to Wizards cause of that sword. Besides DMO is so OP, there's no LoN spec that works for wizards. Those multipliers are so high, LoN is a complete joke for Wizards. Twisted Sword + DMO = infinite damage scaling, as long as u have the support to keep the wizard alive and feed him infinite arcane power.
We can work combinations with other classes to do 80+, but I don't think we will do much more than that without a dps Wizard.
