Suggestion: Encourage Players to play together
League would be more enjoyable if there were advantages or rewards for players that play together.
Every multiplayer game has some sort of mechanism that rewards players for playing with friends, family, or just other players. It helps the game succeed and keeps players attached to the game because their friends play. This will help Riot gain more money and keep players playing league.
Hear me out. My suggestion is let players earn RP (if they win the game) depending on how many other players they queued with and put a cap on how much people can earn a week: 2 People = 1 RP 3 People = 2 RP 4 People = 3 RP 5 People = 4 RP Max of 75 RP per week.
It's not much, but it will give players an incentive to play together. It's also great because Riot hardly losses any money: A player can only achieve 300 RP in 1 month. People that paid before will keep paying because that is only enough for the cheapest skin on sale, and people that never pay will have a chance to gain a skin 4 months or so. Who knows, they may even pay some money to get a few more skins.
Even if you don't go with this, I do hope you add something that incites the average Joe to play with his friends and family. Thanks for reading and feel free to comment.
