After cleaning out my glam dresser, I ended up tossing all the AF gear sets apart from a few parts I know I 100% will want to make plates with, since you can easily re-buy most from NPC. I'm grateful they do unique glams for each job, every new expansion, but it's rough for me to hold them all together since they're for 1 job only, and I only make universal glam plates to save time and energy.
Currently at 650, so I just keep the main tops of dungeon gear, hats, and maybe pants/shoes if it's unique or looks bad w/o a full set. I have the Vanguard stuff on retainer since I spent so much time getting the clothes. I want to add more weapons, but I feel like I always rotate new weapons, so it's not worth it apart from old relics.
However, I do disagree, and that SE is 100% forcing players to buy extra retainers, not even 1 more free one after 11 years since I started, and the 2nd chocobo bag being locked is terrible as it's much smaller already than main inv.
I admit I don't use each and every glam item; just a good portion is from AR, and they are impossible to farm for glams or non-leveling dungeons.
