Career mode!
So after playing many games in my life I glued together some ideas. What if league of legends had a career mode. Let me bring my own fictional player into the world of Esports! I'll never be good enough to play professionally BUT like madden lets you hit the gridiron what if League let you load into summinors rift?? You would create and design your own player, his skill set, what champions he is good and bad on, where he is from, and how he became a pro. You would be playing against legends of the game in Faker,Nagne, Bjergson,Froggen, Deft etc. or playing WITH them. Since no one owns any of the rights to the players look and sound you can get the full Look and feel of pro gaming at its core. Sure the AI would need to be overhauled but with games like Heros of the storm which have their AI rotate in weaker lanes and push map objectives I know the tech and programs are out there to accomplish something like this. You could just design a program for each role such as supp would buy more pinks and focus on vision while the Ad focuses on farm etc. If Riot would be concerned about people not playing it enough look at Call of Duty or Halo games that have a great single player campaign but also focus more heavily in the multiplayer gameplay. This would just be an option for players that maybe don't have such great ping or don't like multiplayer games. You would open the game up to a vastly larger market of players attracting Rpg fans with the ability to upgrade your character, casual gamers, because who doesn't love creating themselves in games. And finally low Elo players, players who probably will never set foot in the big stage. At least this way they get a small taste of that I JUST CLUTCHED WORLDS FEELING. Just a thought Riot
