I am 100% in support of new weapons. Just not as new weapon classes.
We have swords, axes, hammers and clubs as 2-handed weapons.
We have swords, wands and maces as 1-handed weapons.
I would love to see spears, tridents, tonfa, flails, whips, large claws (1h), glaives, asian fans, scythes, giant keys, hell, anything that could fit into the 1H or 2H swinging animations.

Whatever the heck Luso here is using? Sure. We've got a ton of swords, I can wear any of them in my vanity slot. <3 Can't wait for different looking cool stuff.

Thankfully it looks like this is already happening.
We've got a spear, a staff and a blade of grass dagger, perhaps?
