Double Archive
This is mainly for the one handed weapons. For instance, people have multiple costumes for their weapon ( the bow for a ranged class, two one handed costumes for a melee class etc. ), there should be a way to where we can store BOTH ( even if they are the same, like two poison needles prime ) in our archive without having one in the archive and the second taking up space in our bag. Just a suggestion.

Equipment Pre-sets
And also, I notice that when I'm doing dungeons with guildies, and we have to swap roles, there's the "Wait, swapping equips" pause. I think there should be "sets" so to speak. All we would have to do is equip, say, a dps set of rings, necklace, cape, trophies and weaps, and save that to "Set 1" ( have them nameable, of course ) and then have a magic set named "Set 2" and so on. It'd be easier by eliminating the time it takes to find the equips in the archive, remove them from the archive, remove your current equips and then put the new ones on and then change your class. It'd be more of a convenience thing more than anything.
