Add all the game modes as options inside custom game creation
When you make a game you would have a group of checkmarks you could click to enable certain options for the map.
-Same champion selection. -All for one. -Enable URF mode. -Hexakill -Enable 3-10 bans -Set death timers to be 50-100% decreased.
and other options like that.
That is what a custom game should be like period. Want a good idea of what a custom game looks like? Go play unreal tournament 2k4, you can adjust the setting on every single gun in the game. Including what projectile they fire, color of said projectile, rate of fire etc.
This is what league needs, true custom game settings.
Who here can say they wouldn't play hexakill-allforone-urf in one game.
