New idea for new game mode

I really think Riot should make a new game mode. I think they should make it when yo u play on the Old SR and play like the old time champs before all these new updates. I really would like something like that and will be very interested in playing it. I think it's an awesome ide a and I will enjoy playing it. Something they can do is also just let us go back the SR that we all grew up on and know. It will bring a lot of memories and will be awesome. It can be a special event like Ekko and zil fighting and messing up time! (SR= Summoner's Rift)
