Creating a campaign mode for league of legends

I think LOL should make a game mode where you can play alone or with other friends in a campaign mode. Riot does have a bit of a lore, just not that specific, and using that, they should make a story for a single player mode. They could make modes such as using one world as a campaign, like Nox or Demacia, or they could just make a champion specific gameplay. I feel like it would be an awesome addition and a new type of game that plenty of people would be willing to play.
