Since you can glamour a 1 slot robe over a 2 slot cowled robe and it just doesnt display the head, why can we not glamour a 1 handed weapon over the 2 handed weapons and just not have a shield. I dont really see much difference between the 2 things.

Lots of things, like the lightening fate rewards, Leviathan whm weapon etc are 1 handed that actually look nice and I would like to use, but you cant.
