I would say just adding more quests. Like $5 "Quest Packs" or something that would just add a few quests/locations/items/etc to the game.
I don't know, outside of major expansions, I would just like more content in general.
As for the Thalmor, well I would really prefer that just be a fact of the game world rather than something that needs to be resolved by the player. Like the Imperial occupation of Morrowind. It was a big part of the game's backstory and added a lot of color and flavor, but the player wasn't there to somehow end that conflict.
