If you left click (move) and right click (Warpath) almost at the same time (right click a little bit later), Warpath can stuck channeling. It can result in 3 possibilities (it probably depends on click timings):
- it is stuck channeling, but movements behave like there is no channel (character stays still and moves only with left click).
- it is stuck channeling in a normal way like I still keep right click pressed (character follows the mouse)
- it can keep only animation, no damage is dealt and buffs are not applied.
It is not that annoying. On the contrary the first variant is even a nice bonus (and it happens more often to me), since you can move and loot freely. But still it looks like a bug
