too late to edit my last post so..
I think in LoD wwsin, she is using claw hit animation while in spin, and this looks visually more natural and 'impactful' imo.
and problem with what is shown in d2r alpha, wwsin is twirling on single axis, and not using claw attack animation, so it looks off and has less visual impact of attack hitting targets.
again, thanks DHA for compiling these vids for us, among other things.
