The Problem(s)
Eyepatches lack variety and style in a lot of ways. Considering the number of players that use eyepatches is without a doubt a minor number, I fully understand and accept this isn't a concern. But the real problem with eyepatches is how infuriatingly unusable they are by the people that want them.
Right sided eyepatches have a number of options, but class restrictions limit their use. While left sided eyepatches only have two options, one of which is limited by class AND gender?!
The Solution
Here's my take on solving the problem. Square Enix just needs to make all class, dyeable variations of each style of eyepatch (Much like what the Gryphonskin Eyepatch is) and model them for both the right and left eyes. Then, attach the adjustment between the two eyes to the "Visor" emote function. Thereby compacting the eyepatch glamour to its simplest and most accessible form.
