This is my Suggestion For Making ur Matchmaking More Balanced

1. Remove Duo From Solo Q or dont count duo as an advantage and mmr weight . (Just so u know guys when u go DUO or u have duo in ur team u have much worse team and weaker them then enemy just because DUOing count as a huge advantage in matchmaking system right now )
2. make it this way that any player only can pick his mastery level 7 champions in ranked.(it prevents so many smurfs and boosters too abuse a champion at level 30 too and btw tbh its not so bad to force players to learn a champion first then play it in ranked)
3. Dont match diffrent ELO players . Do somthing that always gold players face gold players.silver face silvers.plats face plats.etc... . u can make exception to face someone with higher elo if he had a huge big win streak.
4. Motivate players more for winning. i mean cmon its a video game u can give some more rewards beside the fucking victorius oriana. u are not paying players just give them some more skins and emotes and options to motivate them to TRY more for climbing.
5. make a new system. to calculate in-game factors too. not just kda but all factors a perfect calculator that can realize best player of each team and worse player of each team and best ones lose less LP for lose and earn more LP for winning.(that makes people to not just try to win but try to carry and be MVP )

Here was my suggestion. if u do this im sure 100% ur matchmaking will be so much better and more balanced. yea Que times will be longer but at least u get qualified games. i really respect u guys if u are disagree with me but tell me the reason if u are.
