PvE League of Legends?

What are your thoughts And Ideas of PvE league of legends, would it make it better , worse ? How will it improve league of legends I've always wondered what league of legends PvE would be like Being In RuneTerra , Etc Like imagine a world in Rune Terra where you can play through old story lines like Kha'Zix And Rengar , Jinx and Vi or Starting off making a new character with races such as like Void born , Human , Yordle , Etc . Or joining factions like the demacians or noxus-ians? Starting off in Zaun or The shadow isles or Bandle city; Or Having mentors like Zed Shen or Teemo. or classes like Marksman , Fighter , Tank with all kinds of weapons and abilities I see so much potential in a world of PvE League of Legends and I hope you can or one day will see how great it could be.

EDIT : I know it already has some PvE to it , but I mean more like a role playing PvE I guess.
