Division I can be looked at as the Division with the best of the best. The clan that is victorious in Division I is often the best clan in all of the Regileague. As such, Division I is meant for the Regileaguers that are the most competitive and the best at battling. Because of the competitive nature of this Division, requirements for joining will be much harder in Division I than Division II, perhaps even being invite only. For this reason, it may become difficult for newer members to immediately join a Division I. It is recommended that these newer members first join a Division II clan to better display their skill and expertise.
Division I comes with the toughest competition, but also the greatest glory.
