Barb is my favorite character and as much as I like the new look of the game, I'm really disappointed with WW, totally fucked up in the video I would add that while doing ww during a duel I am locked in fhr animation and I can not move, this it was not in d2lod and I feel that blizzard killed the symbol of the Barbarian -Whirlwind.
As for how to prevent name lock with ww, the show items command could be replaced with another function like force move or change somehow, it's super annoying to do ww and see all the ears on the ground all over the screen, even with nopickup comand.
I will add this comment to the blizz discussion and hopefully they will fix it if they care about it
