I'd like to start a thread here about new big/small features that you would like to see in ESO. Again many of these probably won't be implemented, but I'm trying to think of the features from different MMOGs I've played that I liked.
1) Playing for awhile in Neverwinter, I really liked their player created dungeons feature. It seems to me that would be an great way of continually generating new content for players at all levels with minimal effort by ZeniMax, post implementation effort anyway. As in Neverwinter, you could have a player rating system that would steer people towards the better dungeons and give in-game bonuses to those trying out the player content. As long as the developers put in things to prevent players creating loot farming dungeons and the like, it would seem to be an excellent idea.
2) How about a Reincarnation feature like they had in DDO. Once you hit level cap, it would allow you to start again at level one with some permanent bonuses and maybe some physical traits only available for that.
