Make League of Legends profitable for the players and the creators.
What if they allow an app or a website that is well secured and encrypted, for players to be able to bid money against each other, for example a regular summoners rift match-up 5v5 every player bids in it 10$ the winner takes all, hence that each player will profit 10$. and for League to be able to make money out of it they add a monthly fee of 1$; 1$*thousands of players thats a nice residual. and it will make the game a lot more appreciable and makes it more competitive, and of course you could apply the tribunal system to it too for those who misbehave.
