PLAY OF THE GAME PLEASE!!!!
This would be the coolest addition to LoL ever. Reward those who played well and encouraging players to strive for the play of the game. This would make LoL so much more fun and rewarding. Getting to rewatch a Pentakill, 5 man knockup, amazing ult, 1v3, and so much more. Putting a spotlight on a player's mechanics and outplays during the match or just amazing contribution to the game would, in my opinion, bring a lot of traction back to LoL.
