Not sure if it's been mentioned in this thread but I'd love to see decay added to ranking. Require players to play a minimum of say 10 games per week to keep their standing otherwise it begins to drop as the weeks go by. And make it percentage based so top players stand to lose more by not playing that way they're in queues giving others a chance at them instead of those players jumping out to a big lead and then just never queueing again and coasting the rest of the season.
