Not where you would want to go, but what sort of new options would you like to have?

Things I Want:

The ability to buy perk points (one you have 100k gold and optimized equipment, plus a multiple estates spread across skyrim, there's not much else to do with your money).

The ability to combine the two daedric curses, werewolves and vampires, into one supermonster. Or, the ability to be both at once.

Better Master level spells for magic (ones you can cast one or two handed).

More unique sets of gear that grant bonuses when all are equipped (especially armor sets that are dedicated to the daedric princes).

More new enchantments.

A sustainable flight spell.

More Daedric quests (Hermaeus Mora is cool in Dragonborn and all, but I'd like to see more of the other daedra).

The return of the Hand To Hand skill set (Because nothing says awesome like slaying a dragon with your fists).

More perks.

And a partridge in a pear tree .

Imperial Dragon Armor.

Orsinium and the surrounding area. I woul love to see how the orcs there are and how they differ from the stronghold orcs.

Malacath and different looking orcish gear.
