I think the best elements of Cogs season 3 that should be preserved are these:
Every team plays every week - This keeps clans active and enjoying the game smashing each other to pieces
All matches are best of 1 - This makes the stakes extremely high, increasing the level of competition while simultaneously reducing the burden on casters and the wait on players. With teams playing every week, the losing sides will only have to wait a week to reclaim their honor.
The best teams play against the best teams. Other teams win to earn their place as the best teams while the losers drop down to play against easier foes.
