Make new players better, and reward experienced players for doing so
This idea is stolen straight from team fortress 2 https://wiki.teamfortress.com/wiki/Coaching
Why isn't this a thing? I think new players should be allowed to sign up to be spectated, and the spectator can chat and ping with them, giving them advice. Really, new players need some guidance, and Riot has failed to provide them with any real help. Why not let the players help them?
Players who do spectate and help newer summoners can be rewarded with skins or RP/IP or whatever if they are rated highly.
