Disallowing instant casts on left click seems really bad and anti-QOL

I really rely on having phase run on left click to trigger my trigger wand to cast other things with my build. I am sure others use instants on left click as well. Why was this nerfed? I cant unnerf this with AHK because I play with geforce now. Makes me not want to play because now I have to press a different hotkey every time I move. Is there another way around this? What skills CAN be used on left click - if any?
