There aren't weapon type issues with ranged weapons; anyone that can use a bow can also use a gun or crossbow, and vice versa.
That's also why I said that the weapon type restrictions are stupid. They were put there for lore reasons, but they sort of dropped the ball on that a while ago when they introduced Death Knights. I mean, when was the last time you heard of a Death Knight wielding an unholy rune mace? How about dual-wielding two rune maces?
Lore --> window
As long as they keep it within the weapon categories (one-/two-handed, staves, etc.), I don't see why they can't open up a bit. Weapons have been normalized anyway, so there's no reason to choose an axe over a sword anymore, except for aesthetic reasons. Weapon types used to matter, but aside from a couple of racials, they really don't matter anymore.
