yeah, it avoids controversy--or it's supposed to....rules are sometimes open to interpretation. i'd just as soon have something that i think could be questionable dealt with in advance. doesn't happen often, but i'll always get approval from the host if i have any doubt at all. also saves a back and forth about legality. i hate that. i'd rather argue powers and strategies then spend 2-3 posts trying to defend the legality of an issue.
