Armoire change

[Nezerius]

Minor correction, not all are gained through alt currencies, only the HW ones did that iirc [looking at the wiki now shows that completing the job quests gives the armor as well], the 70 is given by a quest, the 80 is given for free, both 45-50 and the 50 sets are given for doing your classes jobs quests. So if they are concerned about a bug permanently deleting the item, why would they let us put all the event armors that are limited time access in there? that makes less sense than allowing the easily re-purchasable armor in there.

While you're correct that not every AF was gained through special currencies, the lvl 60/HW AF was first added to the Centurio Seal vendor, before being added as a quest reward to the lvl 60 job quests in SB.
Not sure what you mean with allowing easily re-purchasable armor in there, though. None of the AF sets past the very first one can be stored in the armoire.

The armoire is something of a relic of the 1.0 game, with it having some kind of limit on the amount of things that can be stored/shown at the same time. I remember reading that the addition of the Yo-kai weapons caused a few bugs, before they changed the armoire to have multiple tabs.

The armoire is now in a pretty sad state. It is that kind of ARR feature that just did not end up well and are now just... useless / broken.

It was already around before ARR.
