[Unpredlctable]

Honestly, a bank, or any of these other crazy ideas that have been mentioned about adding to the server's economy, is pointless. Zone doesn't have much of an economy, and really it does not need one. You get money, you spend it to, in effect, gain more money, and so forth. There's no reason to store money in a bank because unlike most servers, you don't actually lose money when you die.
And, allowing a bank to be robbed?
eh. sigh.
