Heh, well, I stand by the list. While I own a few unusual dice (purchased individually) myself, I've never seen a standard set of polyhedron dice contain anything more or less than 4-, 6-, 8-, 10-, 12-, or 20-siders, and every tabletop RPG I've heard of, including the now-common D20 system, requires that specific set of dice.

That said, I do think I agree with both your suggested changes.
