Whirling slash disappearing

For whatever reason sometimes when you cast whirling slash it just disappears instantly, i had this occur very often on Jamanra, last boss of second act. Sometimes it disappears after first cast and sometimes with few stacks. All this bricks twister combo.

Same, the skill is like it is having a collision with terrain and won't complete the cast yet it sucks the mana. Seems skills since the patch are very sluggish and do not cast correctly

Same issue

UP,same problem

Hey i have the same issue, WHIRLING SLASH just dissapears, which causes you to have no build up and then no damage, this really takes the fun out of playing the tornado build!!

GGG Please address this issue, whirling slash isn't working as it should, leaving our builds very much broken, since it's the biggest output for our damage.
