I haven't really had an issue with instantly stopping, i just click 1 or 2 hex near my char.
Its the clicking to make sure my char shoots as soon as the AP is enough, that bugs me.
For instance, lets say it costs 5 ap to do burst, i click target while my ap is 2, char will do burst when ap regens to 5 without having to click again, of course you must click again to stack your next attack. I think this will help high ping players and allows you to observe enemy movement and not the ap bar.
If it cant/wont be made that way, oh well.
