a toggle hotkey for Archer’s 0 cooldown skills like Twin Arrow, Heavy Shot, and Oblique Shot will make casting easier. Instead of leaving the mouse/WASD and pressing the hotkey multiple times, making such toggle feature will reduce stress on switching hand position while gaming… I’m not sure if this is only applicable for archer, but i wish it is for other classes.
what i would recommend is add an option of turning HOTKEYS(including non-zero cooldown skills) into a toggle hotkey for auto-fire… doing such, for hotkeys, is easier(to develop and implement, i think) instead of limitting it on certain skills…
