I remember nili talking about that.A centralized regulating body for the certification of events, organizers and players is becoming necessary. The skeleton of one exists with tournaments now acting as feeder-qualifiers for RBW5, it would be nice to see that expanded further as it would end up covering cases like this.
Would be a great idea imo, so you would just have to clarify that you use standard ruleset (+/- some special rules) and it would be less work for everyone (except the inital work to create)
