I agree with the buffer to interact with items, its annoying but I did get used to it. Nothing I would write home about, but it is surely something that could be fixed, its just very minor. I wouldn't stop playing the game over it.
I've seen a lot of comments on the camera and changed player movement, I think your the most passionate(negative) voice I've heard. Most seemed to either enjoy the new camera, or think that the player movements worked out ok because the game was also rebalanced.
Since I never got into ED, I don't have a problem with the camera or player movement. I don't have expectations on how it would play. To those who have never played before I would give the demo a shot.
I like the hud, I don't mind reminders of what I have equipped to a slot. I tend to change them around a lot early in game. It is not taking up a lot of screen space and burn-in isn't possible for me, so thats not a concern. I wouldn't complain about DKS having the onscreen reminders as thats pretty much an industry standard at this point...Your using DKS as a proxy for an argument that is much larger than this game. One thing though, the reminders could fade out after a bit of inactivity.
