Just to let you all know I'm in conversation with Riot to be allowed to host my own 32-team Riot-sponsored tournament.
It will be structured as follows:
32 teams get split up into 8 groups of 4.
A plays B, A wins
C plays D, C wins
Two winners play each other and two losers play each other.
A plays C, A wins --> A progresses.
B plays D, D wins --> B eliminated.
C plays D, C wins --> D eliminated and C progresses.
You get the idea. Win 2 to progress. Lose 2 you're out.
Remaining 16 teams just straight elimination single-game affairs. Final/3rd place playoff best of 3.
Prises for top 3 teams.
Will be Riot points of some amount, still up for discussion.
