Barb WW question...

I just saw this comment and I wanted to know f someone could elaborate more for me:

"A little trick that most people don't know about WW, the right hand determine most of the damage and left hand determine speed."

Thanks for any insight.

that makes no real sense, because if you look at your ww dmg, if using two weapons, it shows two fields of dmg. Im almost positive the speed is determined by your ias, hence creating the frenzy ww barb.

ias in case you were wondering is increased attack speed.

Hehe, I know what IAS is... I saw that actual post and I pasted it from Battlenets forum page. And a few others wrote after it, explaining it better, so I'm guessing its not total bull shit, but I couldn't really get a grasp for what they were saying.
