Bonestorm Double Casting

The issue might be present with other channeling skills but have only encountered it with Bonestorm.

The ntended way for channeling skills to work is that when you hold down the button your character moves slower as it stays in the casting animation. However, if you quickly press and then hold down the button you can continue to channel bonestorm while moving at your normal speed.

I noticed this last night and confirmed it is very reproduceable just now. You are able to move at full speed while channeling the skill to full strength.
