Traps - Sure. Another means for my dark brotherhood character to dispatch targets.
Guns - No, and anyone suggesting this in an Elderscolls game deserves to be flogged.
Dual Wielding - Yes please. I love using two weapons at once. And for crying out loud people its a game. Screw practicality, this is a
FANTASY setting.
Wands - Why not? I wouldn't mind seeing them. Also, why must everyone go "this is not Harry Potter?" People, J.K. Rowling did not invent the friggin' concept.
Fist Weapons - Again, sure. Claws, knuckles, etc. would be nice to see.
Other - Polearms, Flails, Thrown Weapons (knives, stars, etc.).
