It has come to my attention while I watch my friend play with his guns that his attack speed vh - max guns are too hard to fire, this is because of the massive speed he has to click the mouse for maximum potential go.
Now, perhaps there should be a button that, when held down, doesn't charge the attack but instead spams the attack button constantly at maximum speed (think turbo controller).
This would allow easy usage for those more fast guns when made faster via UV's and the like.
This, all of this.
