I would really enjoy any of those 3 things to be hosted.
1. Protect the King but not in a small format. 7v7 or 8v8 would be cool.
2. A normal tournament but in a bigger format. Maybe 9v9 or 10v10. It would be easy to get at least 12 Teams.
3. A GF-Team League like MarxeiL planned to do it sometime back. With 2 Divisions with both 8 Teams. We clearly have enough GF-Teams at the moment and I think with splitting it into 2 Divisions it would be extremely interesting for High and Medium Tier Teams. The format should be a classic one, either 5v5 or 7v7
