Rebel that's a way of doing the lower bracket but I'm proposing rather just to have a separate tournament playoff completely for losing teams from the group. The problem with your idea is how would you really decide what sort of advantage to give to the upper bracket, because it's not like CS where you can just grant them a map or something of the sort. Otherwise if you don't give any advantages then you're having teams potentially replaying each other in the finals which is equally nonsensical. By just making a completely separate loser bracket it's going to be a similar tier competition between the teams in it and tough luck for upper bracket people I guess.
