Here's a thread to kick around ideas for improvements to the game, regardless of how practical or impractical.
Dynamic Level Adjustment - As best I can tell the game currently totals all of your numbers and then scales it down by the appropriate amount. It would be better if it adjusted the player and each item separately. So a level 80 character in a level 60 zone would have their stats and their level 80 items downleveled by 20, but a level 75 item only 15 and a level 60 item unchanged. This would allow a harsher adjustment overall without unduly penalizing those with gear in between their character level and that of the zone they are in. Theoretically you could intentionally use all lower level gear in lower level zones and still get full effect if you wanted.
Camera Adjustment - I really dislike that the camera is zoomed in when you are against a wall (or tree limb, or slight outcropping) and that items in your field of view between the camera and your character block your view. What I would prefer is that the zoom level stays static and that any items between you and your character become "ghosted".
