Mundo Q is less responsive than ideal.
Since the lastest patch, the Q seems delayed or entirely unresponsive on rare ocassions. I've had difficulty recreating this due to time-constraints, but I'll report back if I have time to test in a bots game. It feels like it's related to excess right-click inputs, at the very least. I've had similar issues with his E and R, but not consistently enought to confidently report it.
