I think it would be interesting if per say all 3 could be used. when you are created or for the already existed players you would get a token. Take said token to a shop or what not. You would then have the option of picking one other guild that used the CMS you weren't useing. Set it at like 50 for dev ratio or whatever the number means and you can then go to said guild and train. You would only be able to train skills in that catagory also. So me being a tinker could pick lets say enchanter and slowly learn the skills and spells of the enchanter guild. Will i ever get powerful over it, prolly not. Since the dev gain would be so minimal that it would take a few years to even get very far.
