Whatever you are truely looking for, I assure you that you don't need WW for a zerker build. Not even one point. For crowds, all you do is stun with War Cry (which at high lvls i.e. 20+ gets over 5 seconds of stun, even in hell) or if it gets too ugly, just Howl and make everyone run.
WW is not crowd control.
Also, I don't know if you have played a barb yet in v1.10, but they are very different from v1.09. Sure WW barbs still work (I have one to prove it), but they are more item dependent than ever. Zerk is great because the best weapon in the game for it would probably be a Steeldriver, and that can be found by NM Meph quite easily (but don't tell NF that).
v1.10 barbs (non-WW ones I should add) are all about crowd control. Many builds incorporate War Cry, Howl, Shout and Taunt into their builds so they can kill more effeciently. Also, the use of warcries makes your barb less item dependant. Who cares if you do crap damage if everything is stunned for 5 seconds?
I rest my case,
