Making it better
What if Riot gave IP rewards for completing tutorials?
I'd really love to see a quick tutorial released for each role, and a better demonstration of runes / mastery pages. I also firmly believe that a large part of why this game is full of players that rage quit, troll, or feed is simply because nobody really knows how to play.
It's especially hard to learn roles with the smurfs yelling and screaming at you for being new, and I feel like making it worth while to play through some boring tutorials would really help motivate people to play through them once.
Being IP and not RP, I don't really think it could be abused. You get rewarded IP for playing the game anyway, so it would only make sense that you got rewarded for boring yourself to death and developing simple MOBA skills.
