disable left+right click to use special?

this is such an egregious control mistake. moving camera with right click, attack/charge with left click. but combining them uses your special? i haven't found a way to disable that specific behavior. changing the camera button to something else feels so unnatural, but then the camera control is inextricably tied to a combat move. i was considering writing an autohotkey script to disable right click while left clicking, since i can't think of any other way. any suggestions?
