Deadric Worship-DLC / or just quests
That would be amazing where you starting some quests by choosing Deadra or Aedra to serve (or multiple)
Gaining some Permanent small bonus ,
like : 5% to pickpocketing / lockpicking if u choose nocturnal and if u belong to thiefs guild
or 3% that guards or people ignore if u stealing .
or Aedra + to Regen or to stat !
and/or improving just a bit power of ur skills / crafting etc
and
Dradric Artifacts ! better than weapons u can find in dung /WB/ trial etc
+ with that adding some more enchants also with it .
Also it would be Great if you cool get grip and get us More Abilities / Skills / Spells / Alteration School and other / Single swords or Single sword and Battle Mage Staff (normal with blade in the end)
Whip would be great weapon / same as Spear - or Spear and Shield /sword , Throwing Javellins , Throwing Axes / Hand to Hand Fight ( so we could feel more like in other Elder Scrolls games)
and
Battle on Horses in new Type of Armor which would be Plated with Tower shields and one-and-half handed swords (Two handed - as one handed but with tower shield )
LAst Thing you could add would be More Vampiric /Werewolf Quests - leading you to Rinse in their rank and Power
or Militar quest line where you ranking up through loads of dailies vs NPC's from opposite fractions , and loads of normal Q , and in the end you decide about troops movements !
I will always need for more classes in the game... Monk Kung Fu Khajit - with martial art staff and straw hat, Alchemist - throwing bombs and potions , Bard as support rather then healer, and Arificer and Arifact collector of alyed and dwemer ruins
