Story mode idea
I was talking to a fellow league player and we were discussing how we hate that so often we get a player on our team that refuses to work with the team and I shared the following idea with him.
What if Riot created a story mode. And that mode comprised of playing through a characters lore. As rewards for completing each characters lore you earn a small amount of IP and possibly an icon or a skin based on their lore (such as pre void Malzahar.)
I feel with the new lore they have been writing throughout the past year would give this mode a lot of depth and a decent amount of play time for each character.
