It would be hell if the offers were automatically accepted, can't think of that. However I think that they should implement a "witdraw offer" option, currently I have all my remaining 14tokens placed as a bid for a corner specialist MC, but meanwhile I already found a better MC, bought him for two tokens, and looking for a DC/DR. There's a good one coming in an hour and a half on the TM but my tokens are blocked for the following 4 hours as it seems. Well, managing my tokens apparently is not my strong point.
