Ok matt, as requested I am here to clarify. This person is asking for a bank (Like a vault) that will keep a certain amount of resources guaranteed safe during an attack (Like a vault in boom beach). However, if this was intended like a clan bank, where resources could be deposited/drawn out by other members, yes, it would be ruled out under trading resources.
I would actually appreciate this to keep my resources safe, but don't think it would be good for the economy because it would mean less loot available to be taken during raids.
Once again: Not ruled out. This is an idea for permanently keeping resources safe, not trading them.
