Video that i think should be in the home screen of league of legends

I think players today dont play for the fun and the teammates they play for themselfs and they only know to rage on the game but i dont think that was your point when you created the game so please put the video on the homescreen so some of the players can see it and try to play better with their teammates.

P.S. : Love the game, but sometimes my teammates spoil the game when they nonstop spam and never play as a team. Thanks for the time .
