Problem:
When you want to play one of your characters, you firstly need to transfer all usefull gear to that character.
Normally, it's not big deal, but when you use your alts often, it becomes annoying to transfer gear between your alts all the time.
Possible solution:
I suggest something pretty simple here. Make a crate (or whatever it name would be), where you can put your items, like you do in armoury now.
Items which are added to crate appears there, you can check their stats and of course remove them from crate, just like it works with armoury.
The difference is, if item is in crate, you can equip it (on site and in game) on every char that is created on your game account same time.
So you put eg. Armor +3 into crate, and when you go to Inventory -> Gear site, it appears in listbox as item you can equip for any char you have.
This way you won't be forced to transfer gear between your chars whenever you want to play one of your alts (I do that pretty often lately).
Easier solution:
It would be easier to implement "share" button within loomed items instead of crate. When you click "share", item becomes visible for all characters on account.
Other solution:
Simpler would be to count all loomed items as account items, not character ones.
But I guess it don't work like that, to not exceed item limit for player in game?
