Surprised there isn't more love for paces. I think paces are excellent. It's about 5' anyway historically. It's has the archaic feel (because it is), and if you are thinking in battlemat terms it makes sense that you'd traverse a pace in order to shift or otherwise move one "square's" worth. Remember the 5' "step" from 3e? Now you can shift X paces. It's a unit of heel-to-heel land-based movement, so if your stats say speed 6, you move 6 paces in a round. That sounds fairly natural to me, definitely less crunchy and boardy than squares. I'm fine with squares as a term specific for area.
