Whirling slash bug / changes

Whirling slash issues:
1) You get stuck on everything... everything
2) Elevation.. monster higher or lower will get knockback but no damage
3) Could we please get rid of the effect going away when you move to far out of it? QOL, but does anyone rely on the detonation effect? Its brutal to get a good thing going then have it go away if you have to zone, monster moves you, roll or blink out of it etc...

Thank you
