"All the Cash Shop and Event stuff can be put into the Armoire"
No, only items related to achievements can be placed there (like seasonal event items and AF1 gear sets for example). Mogstation/FFXIV Store exclusive stuff cannot, because there's no achievement related to those items. This is why every single seasonal event gives you an achievement when you finish it's quest, so you can place the glam there and also be able to rebuy the same items from the Calamity Salvager



"invest more thought into really obvious QoL changes. Like that Market Board"
Care to at least explain which is the issue with the marketboard?
