It's largely dependant what class I am playing as to if I want it or not and also just for the social aspect so i can type out a message and not have to worry about standing there doing nothing while I do.

How would I implement it? Well make it toggle on/off for basic attack by holding down 1 for a few seconds to toggle on/off. When on it would only use the basic attack once your stamina bar is completely full then wait for it to fill again then launch basic attack again and so on, easy.
