Drop the light system and go back to how it was during HoW. HoW allowed diversity in the tower, no one looked the same unless they just liked rocking the VoG raid gear. I personally don't like the fact that if I want to look different I have to play the endgame content so many times and rely on RNG to drop the correct item I need, also at the right light level. It seemed like a cheap way to keep people playing the same stuff over and over.
