(1) To be able to pull stuff from one's personal Bank to equip it (and refusing to do so if there is not sufficient inventory space.)
(2) Increased armory slots to be account-wide, not character-specific. 1000 crowns to upgrade just one character's number of builds is silly. Even if the individual builds are character specific, 1000 crowns should buy a new slot for ALL characters, not just one.
(3) A "Delete Build" option which reverts any given build to empty, without changing what the character is wearing.
