It would be pain in the ass for me to split clan to four division. But idea is not bad, so let me give a counter offer.
Remove clanners and put a new system called League Squads or something. To summarize the system:
> Each squad will have 5-7 members, a number will set based on poll or stuff.
> Each squad has 1 season lifetime. A new squad has to be formed each season.
> Let's say each squad has 6 players, next season max 3 players can be same squad again. Like Squad Z has members: A, B, C, D, E, F. Next season maximum 3 of these guy can be same squad again. This will encourage people to team up with different people and prevent OP people to dominate every season.
> Maybe something like you cannot quit squad after first 2 weeks of league and join another. Just be loyal for god damn 60 days(+PO if your clan goes for it)
> Clans and squad are separate groups.
Just a thought.
