To follow up my negative post, I have a suggestion.
What if select skills only were allowed. Say some of the lower level tinker runes, herbal lore, poison lore, but not pick locks or something like that.
Perhaps have a lower cap on said skills. For the magic guilds perhaps only allow people to train spells to *4 and no spells over level 15 or something like that.
This would allow for some variations but would keep anybody from ever replacing another guild.
