New game mode!

Hello everybody, i was going on google and trying to find a build generator. I found one generator that was pretty old but worked.. when i saw the champion art/face it reminded me of the old league, (season 1-4) These seasons was the best seasons and i just though that it would be cool if Riot made a new "Mode" there you could pick a season to play and try it out.. because i really miss the old league.. Thanks for reading and please tell a rioter about this concept :P <3 Sorry for my english
