Thinking about it, I think Monks get the most diversity in the game in regards to weapons. Of course there's punchy things but there's claws, tonfas, even extendable hand-swords.

Would be neat to see every class have that level of diversity. Sure an axe is great but how about a greathammer? That'd be neat too.

As for Dancers, I'm not seeing too much reason as to why they can't throw different things. Just have the weapon held in a way that matches the idle animation: Multiple throwing knives in hand, handle for a boomerang, etc.
