I would also prefer the desktop icon of the game to be the one from the SB benchmark (the red-black one which has a flatter design) by default.
The ability to change the log in screen to any of the older ones would be very nice.
And as we are at it an option to cycle between them randomly at every start up.
There is a strong feeling of nostalgia for older log in screens in all MMORPGs I've played which change them at every large update.
