I'm having a problem w/ the player cast bar. I'm not sure if it's been said, probably has because it's pretty obvious to anyone who spams their keys.
For example: If I use steady shot, the casting bar will come up. If I hit it again, the player casting bar will disappear. It won't stop the cast, just the bar will just vanish and the steady shot will still go off.
Tested w/ various layouts.
