i don't really get what the deal is with these altmer armours. they're light armor, they're a little lighter than leather and a little stronger; but, they're large sheets of metal covering your whole body, like heavy armour does. why would anyone restirct their movements in a metal case with a material which is barely better than fexible leather alternatives. when you start comparing sheets of metal too pieces of skin you have to wonder what the point is. then there's glass. even if it is super light it's still bulky and difficult to work with. when compared to iron armour which may be heavy but gives you a whole range of movement you couldn't get in glass with those big shoulder protectors.
even further, surely scaled armour is about as heavy as iron. surely. and don't get me started on dragonscale, covered in those super heavy dragonbones.
