League Of Legends Story Mode

Hey guys! Today I'm showing you my ideas of League Of Legends Story Mode! I mean not Story Mode in most games: doing missions and things of this sort. I mean you choose champion, then you fight 3 or 4 co-op sub-bosses and they are in extremely hard mode. You and your enemy have to reach, I don't know 5 or 10 kills.And when you beat all bosses you unlock your character's ending. And this give you new quotes on this champ 2 ap and ad boost and 30 bonus health. Is this bonus too much? Or maybe you unlock secret items that you can only purchase when you complete character's story.Tell me which is better. And soon I will update ideas for some character's endings.
