I had an idea today. It involves these five ranks, and possibly more, and they will give your name plate a different color and the letter that the rank starts with in front of it. They are:
Default, no letter at the end, White name plate, wizards level 1-10 Mortal, Purple [M] at the end, Purple name plate, wizards 11-25 Voyager, light blue [V] at the end, light blue name plate, wizards 26-40 Chrono, yellow [C] at the end, yellow name plate, wizards 41-60 Timelord (Dr Who reference), red [T] at the end, red name plate, wizards 61-
Reply if you have any other ranks that could be after Timelord, or any other ranks in between. Thanks! (This could also tell you if there is a puppet team in a PvP match, for example three Chronos and one Default. More of a PvP Puppet noticer than decoration :P)
