Clicking is bad, though your explaination of why is actually quite a ways off. In terms of performance it is actually significantly better today than it used to be. Performance differential between keyup versus keydown events can be ignored because of the spell queueing system. So the fact that mouse input is always bound to keyup (because keydown can be used to initiate a selection, keyboard doesn't have a dragging mechanic, the final result of a mouse action can never be determined just by the keydown event). As far as simply executing a DPS rotation is concerned, clicking can perform identically to using keyboard buttons because of the spell queueing system. It's in the greater dynamic of gameplay that clicking falls behind. Because the mouse is the ideal method of camera control and steering, whenever camera control or steering mode is enabled the mouse cursor is disabled meaning you can not click on buttons while doing this. Where as you could still use keyboard buttons while mouse steering. This increases performance by delegating functions to their ideal components. Mouse turning is ideal, and because clicking can't be done while mouse turning keyboard buttons are ideal for executing actions.
