I assumed you meant, given the context, if the rule changes appreciably affected the meta, i.e. the way the game is played. If you zoom out far enough, all sports have the same rules, contests between humans with a physical component. The rules for swimming and running are similarly changing constantly. Google the controversy about the faster water in Beijing that was used to cause more records to be set, or the rules about shoes in running. The fact that someone who doesn't know about a sport thinks it's not changing doesn't mean it isn't. Ignorance does not convey some kind of deeper insight.
