See this right here is my biggest problem with this whole thing. Why is it that any given player's elevation of their personal expression should trump anyone else's ability to play the entire game? The opinion here is of such a hard stance- 'if you don't like my pixels and don't tolerate them, then your option is to not play the game. you don't get to run the dungeon. take the entire 30 minute penalty.'
While I don't believe that any rational person playing this game right now would actually leave a dungeon for a reason as petty as someone else's glamour, (except for maybe that one guy who threw a temper tantrum about Peloton) it's somewhat stark that people are actually taking the side of that their personal expression should trump the ability of someone else to enjoy the game in a way that's so ridiculously non-intrusive that it should fail to matter.
This is why I suggested the artifact gear- if the suggestion was to have hilariously ill-fitting unglamoured sets, or a setting that put everyone in the data center in a bikini and clown shoes, and those screenshots started becoming the norm on image boards and such, then yes, I might agree that this presents a problem. But to have such a critical lack of perspective that someone else opting to not honor your pixels should even potentially mean they have to essentially opt not to play the game with randoms any more, rather than toggle a completely unintrusive, completely client-side setting that changes nothing for you?
I hate the WAR AF4 but I would not spare a single, solitary thought in the middle of my 12 minute expert roulette involving three people, who I will never speak to or interact with again, to actually say 'boy it'd sure be damaging to my personal worldview if these random strangers who have no attachment to me whatsoever didn't see my curated outfit on the character I hand-crafted to appeal to my own aesthetics'
Merely having the option would change nothing and be used by maybe 5% of the playerbase as an accessibility tool or aesthetics modifier, so I can't see a rational reason why they wouldn't add it other than that it might teach a few of the Limsa socialites some humility.
