Matchmaking

Have you ever had a level 10 friend who wants to play pvp with you, but when you guys enter a match, and end up against a Gold/Plat/Diamond because of your mmr or rank? I find this kind of unfair for your friends, so i was thinking there should be an Elo selector for your games, i'm pretty sure you don't want a Silver or higher player Being Fed off of your friend, i think an Elo Selection should be added so players can choose the best matches for their friends who are fairly new to league, i got one of my friends to play league but since i have a high mmr he ends up struggling when we play pvp, hes level 26 now but i still feel bad for the times he had to struggle, and i don't think other players should go through the same, In game we usually go bot together, but sometimes matchmaking will screw us up and put barely any high level players on our team while the other team has Silvers or higher on theirs, i find this a discouragement to to me and my newer friends wanting to play a game together, so an Elo selection or Better matchmaking would be very much wanted right now.
