Colored gear with specific classes.

Yet the fact remains that people wanted more ways to distinguish one class from another, so what we had wasn't enough. That has been one of the biggest complaints of the game since release.

People were complaining that mages could wear plate armor and gladiators could wear robes, which blurred the line between classes. People wanted armor types to be locked down by class, not color. The ability to dye your equipment the color of your choosing was something that people actually liked.

SE took it a step too far by limiting color. Class uniqueness is expressed enough via armor type. Color should be a choice to show individual uniqueness.
