I want an super horse, like Shadowmere, where you don't have to do the DB quest line to get. You know, for my lawful-good characters. Or maybe even have it happen that when you finish the DB in the alternative way, you could still get Shadowmere and go on a quest to have him transformed?
I like the idea of improved and/or additional smithing, like TC mentioned.
I would like to see them do something in the way of quests with the Vigilant of Stendarr.
In case you haven't guessed, I like to rp mostly good characters. I was kind of disappointed in that when you make a certain decision in the MQ, the Blades won't help you any longer. So, I hope they might expand on some of the decisions made in the Main Quest and the Civil War quest. They both seemed so unfinished.
