It's not as if I've got a horse in the race here since I don't think I've ever actually willingly looked at another player character to see what they were wearing, but it's just an option, right? Having other people have the option to change what they look at and see would affect you personally just about not at all.

Don't get me wrong- I 'get' glamour and self expression and in fact most of my posts are in favor of that the current system of job-based glamour restrictions renders the system incomplete, but arguing against the option to tailor the game's appearance to your own needs comes off as a little...

Well, where SHOULD your ability to self-express be limited by someone else's to not see it? If it's a setting that only affects them, client-side, and you'd never know that they see you personally wearing the RDM AF4 instead of your actual red mage glamour, then what's it change?
