Re: Why doesn't 6e use hexes as a unit of measurement?
Yup. Especially since Steve had the change planned since before Cryptic approached DoJ about CO.
It requires rethinking things, and can be difficult for us grognards to wrap our heads around, but it adds flexibility to the game. Of course I'm an odd duck in that I've run games in 4th edition and earlier with unlined maps. No squares, no hexes, just maps and rulers. It worked great.
