Daggerfall didn't even have medium armor.If the skill was phased out of Morrowind and all the armor types were divided accordingly (bonemold to light, adamantium to heavy..etc) , i'm sure you wouldn't have felt like medium armor would be a necessary aspect.
This armor is native to the ashlanders of Vvardenfell...mainly because its light and resilient. I doubt it would be proper for a native of Skyrim to wear. It'd also serve little use in Cyrodiil.
Due to exterior cell constraints like cyrodiils cities, it wasn't possible to add it. Its basically the equivalent of not being able to levitate in Mournhold (the land around you is not rendered.)
In order to have massive cities it was important to load them in a seperate space or cell so that distant objects and the like did not have to be rendered, thus increasing performance. Who knows what the future holds though...
i agree with most of what you said.
i would like to see medium armor return though, it adds more variety, and there are armors that can't be considered "heavy" or "light", but if those armors aren't in the game, then it would be alright.
levitation should be brought back at the sacrifice of graphics load, ect.
about chitin armor...there are books about chitin armor in skyrim so i don't know why you are trying to dismiss it. here's lore about chitin in skyrim

"She directed her guard toward a ruined old keep on the frozen isthmus of Nerone, across the bay from Gorvigh Ridge. Jutting out on a promontory of rock, it was like many other abandoned castles in northern Skyrim, remnants of Reman Cyrodiil's protective shield against the continent of Akavir. As they reached their destination and made a fire, they could hear the army of the warchiefs of Danstrar behind them, making camp on the land southwest, blocking the only escape but the sea. The soldiers assessed the stock of the keep while Beatia looked out to the fog-veiled water through the casemants of the ruin."
"After a few minutes of searching and matching pieces, the guards presented two very grimy, scuffed and cracked suits of chitin armor. Even the least proud of the adventurers and pirates who had looted the castle over the years had thought the shells of chitin beneath their notice. The soldiers did not dare to clean them: the dust looked to be the only adhesive holding them together."
"The rocky shore to the Ridge still looked at eternity away when Beatia felt and heard the first volley of arrows. Most struck the ice at their feet with sharp cracking sounds, but a few nearly found home, ricocheting off their backs. She silently offered a prayer of thanks to whatever anonymous shellsmith, now long dead, had crafted the armor. They continued to run, as the first rain of arrows was quickly followed by a second and a third.
“Thank Stendarr,” Ascutus gasped. “If there was only leather in the keep, we'd be pierced through and through. Now if only it weren't... so rigid...”"
so yea...there should definitely be chitin armor in skyrim. if not then i hope you get struck down by arrows in your nordic leather armor. :deal:
