We all have seen how the brackets work, they are separated into quarters. Usually you play one person to advance, then winner of the one next to you. with that said you can get lucky and potentially avoid certain players.
Well what I propose is having to play every person in your area (quarter) the player with the most wins advances after having played everyone once. For example if there are 8 people in your quarter you play then at any available time, in no particular order. If you 7/8 matches (say you just couldn't beat that one guy) and that is the highest percentage, you go one to play the guy who did the same on your side. But best of 3.
Final 4 get prizes, winner of all gets the most.
