Riot should delete half of the champions to rebalance the game

The game has become so bloated with champions that there isn't enough room for everyone to be viable anymore. Instead of the players getting increasingly frustrated every season with fewer resources to succeed, there should be somebody with enough power at Riot to do what has to be done and simply wipe out half the champions from Runeterra. They could even make a fun event out of it like when GP was killed off (until they cowardly brought him back).

I know there are going to be people upset by this because they will feel bad that some of their favorites will be gone, but that's why we need one Rioter to have the willpower to go against sentiment and do what is best for the survival of the game. Ideally, they would simply make the elimination a random choice to avoid any people getting upset about bias.
