That would break all kinds of useful, non-obtrusive macros, like macros for putting marks up on your allies, macros for buffing, macros for Symbiosis (ok that's going but still) and the like, macros for life swapping... Is @party1/2/3 also bad?
EDIT: Btw, I have smaller hands than my GF, so it's hard for me to hit as many keybinds as we need now - and even I think that's a bad idea. (My ring finger is less than 8cm)
