It would be nice if the graphics and sound were pre-rendered before showing. What I mean is that, there needs to be a "loading" screen for the user interface so that the elements (images) don't just popout one by one as they become available. It would be nice if after a loading phase, the game would then be fully visible.
In some cases, I find that this should also apply on the login area. The character selection screen is loading the interface images one by one which isn't quite pleasant to see.
