So I've been reading that players used to queue in dungeons and CT, take the items they wanted then they would quit. I also have been hearing how people would want more use for the armoire in your inn. Since there's no "official" in-game suggestions and we only have the freedom of posting on the forum, i wanna put my thoughts.

Loot Pool for Dungeons.
A window openable by clicking on a tab that would appear in the space where a player would get player invites or friend requests. As a player keeps playing, it shows a list of all obtained items so far from chests and what player obtained it. Also, a total count of the gil obtained in the party. However, your obtained loot and gil is only obtainable after the instance ends.

More Detailed+Spacious Armoire.
This suggestion could be a bit complicated, but let me see if im able to detail it. If we were to go the armoire right now, we would see tabs on top, such as Artefact Armor, Season Exclusive Armors, Event Exclusive, ect, however this would completely revamp the current armoire.

Instead of just seeing the the currently stored equipment, it would show showable/hidden clickable tabs, and in those tabs, it would show all the gear. Like for Example:
In the Artefact section, there wouldbe tabs showing the name of the Jobs the armor is for. And then it would show how many pieces the set has

PLD
-Artefact Set 1
-Artefact Set 2

You choose the set you wanna see, and it gives you the currently stored gear. Note, to prevent spoilers, it wont show the name of the gear nor the stats.

In the same way, you can give a "Dungeon Drops" list, divided by dungeons, not by class/jobs, since the loot list for the dungeon varies. Also, since it varies, you can at least show an icon of what the equipment is. A weapon, chest or ring, per example, and when you store it in the armoire, it will reveal it on the list.

Course, its not a completely detailed suggestion but I guess it gives people an idea.
