The vanilla textures and character models look very dated in this game. Square Enix can learn from MapleStory 2 and host a first party mod archive that allows players to create mods that add hairstyles, body features, altered glamours to the game in a SFW way. This had great success in MapleStory 2 and although the rest of the game was crap this was one feature that I wish to see in FF14. There are a lot of SFW mods that make the game more beautiful like HD hairs, HD faces, HD eyes, modded glamours that might not be lore-compatible but still look awesome like Nike boots.
Since this game is highly focused on glamour as an endgame, Square Enix should exploit the massive amount of free labor in the playerbase. There are tons of enthusiastic modders who are willing to create glamours and HD uplifts for free. Officially hosting the SFW ones and advertising it as a selling point is basically a very cheap way for Square Enix to attract more players to the game.
