I've heard a lot of talk about a potential exploit by which people are acquiring all the tools in the game. Basically, they create a char, acquire a basket and dump all their tools in it. Then they delete the char, and keep going until they have a bag full of tools for their final character.

There is an easy fix for this. Simply allow only one character delete per 2 days and its solved. I'm not sure if this has been suggested or implemented yet, but its small things like that which really unbalance an entire game world. I think all of those things need serious attention before release if they want to attract new players who might not have access to such exploits later on. This was a big problem in Darkfall.
