I'm not sure if this has been mentioned already, (the thread is moving too quickly to keep up with at the moment), but I think it might help a lot if they gave us a client-side option to always show the highest quality textures for our own character. We want to be able to appreciate the look of our characters, and it's hard to do that when the textures appear blurry and washed out.
Sure, it'd be nice to see other players with those textures, but I understand where they are coming from and am willing to sacrifice that for performance.
