You cant even use it with a 2 hander equipped
As for its functionality, it is essentially a beefed up Hail of Furious strikes, it even has a very similar animation and sound effect
Oh god.
This thread needs to be stickied and everybody forced to read it before signing up for the forums with a disclaimer saying "DON'T ASK STUPID QUESTIONS LIKE THIS."
Seriously. Thats 40 wasted points just to get WW on a 2H build, and the damage output of that is going to be pretty damn weak.
I will tell you right now that using 2her for WW combo will be LESS damage that dual wield. This is because dual wield will hit with BOTH weapons as you spin around. Also you need to look at your weapon damage... upon doing so you will see that 1hers hit harder (when specced right) than 2hers... And you have two of them giving the chance to proc an OH attack... So... Please for the love of god, don't waste the money trying this, just send the 2g to me in an in-game mail and save yourself the trouble.
