Rather than playing the same 5v5/6v6/7v7/8v8/9v9 (pick your poison) every month, would be nice to have a competent admin team stepping-in and organizing an actual group fighting league in September. You could prepare everything during the summer and have it ready for early September, the exact same way the Cavalry League is planned.
Would be nice to have an event which rewards consistency over a couple of months rather than a one-night performance.
