I only disagree with two of these.
Rare unenchanted robes, & high cost spells.
I'd rather have some unenchanted robes that didn't look like crap, & were easy to come by. And high cost spells? Spells that work would be nice, why would I want a spell that costs even more mana, if I know casting it really isn't going to do anything in the end?
As for things I, in particular would like to see?
1.Some decent factions, I'd like to be able to join a faction that actually has advancement, as it is I can fall asleep in the lobby, & wake up King of the Werewolves.
2.Bringing back teleportation, instead of pseudo-fast travel though, make it a combat tactic. Short range teleports.
3.More unique items. Especially if they bring back some of the older artifacts.
4.Silver-smithing.
5.Alchemical Bombs? Maybe?
6.New, & useful spells.
7.A dependable mount, for good characters. So far we've got flaming purple demon horse, & undead assassin horse. Bring back the unicorn.
8.More houses, the only one I really care for is Vlindrel Hall.
9.Factions that actually do something. The Vigilants, the Psyjics, even & especially the Thalmor don't actually do anything. They're all just there.
10.Werevultures.
Now granted Dawnguard could concievably take care of about half of these.
