I think original COH hotkeys are just fine..., they are quite intuitive: like "N" for nades, "R" for reinforce etc..., ofc some doesn't fit such model(like "T" - retreat or "H" - stop), but its not hard to just remember those.
Very nice video all togeather, every new-comer or player willing to improve his way arround the battlefield should def. watch this
if all the important original hotkeys are implanted in the backbone you are possibly right but come on ! tactical map on "numpad 0" that sure as water is wet do not suite a right handed person.
