What would this change entail?
A prolonged and larger Clan War League (4 weeks/16 clans/15v15) with more on the line and more continuous battles for clans to improve and adjust. The first 3 of the 4 weeks would be regular season, where clans face each other off and compete in wars won -> (if wars won is the same) star gained -> (if that still remains the same) stars difference. In the last week of the CWL, the bottom 8 clans would be eliminated from CWL and could proceed with preparing for the next season or start regular wars. The top 8 clans that finish would be able to compete in an elimination format where the top clan would face the 8th, 2nd would face the 7th, 3rd - 6th, and so on... Eliminated clans are eliminated from the tournament and free to start regular wars. Promotion/demotion of the this format could remain the same as the current format, but instead of 2 clans being promoted/dempted, 4 clans are promoted/demoted because of the larger clan pool.
This opens the gate for regular players to partake in competitive play with their friends rather than custom friendly wars introduced by the community.
Change to current CWL required:
7 days -> 28 days
8 clans -> 16 clans
None -> Elimination
30v30 -> Cancelled
