What might be a good idea is to have a closet where we could put up to five items, for example, that could be accessed by all our characters.
This would leave the chest with all our saved items still there too.
I have heard others talk of being able to trade items like we can treasure cards now also. This would be ok for me because I could give someone my stuff to hold and give to one of my alts. But I can see where this could lead to problems for others if they didn't have someone to safely give their items to, asking them to give to their alt.
Differently would love a cross character bank. it would give reason to hold certain rare drops of classes you can use too. For some reason those this seem like it would be coding nightmare though.
i really don't think it would be a nightmare because if you have crowns for your account it shows up on all your char in the account. i saw that they where thinking of added a trading system awhile back but no more about it since then a post by (Ambrose, are Graygose)
