plat/diamon rank players queuing with low ranks in normals

this has been getting on my nerves lately and i wish riot would really do something about this to make the game better. first of all dont throw my own rank at me just to discredit me. i just really sick and tired of high ranks queuing with low ranking friend to boost them or just for the lols and seal club new players. just now i lost a game to a plat rank player who rerolled the account and only has 326 wins. my mid laner was silver with the same amount of wins like come on. im also tired of those plat/diamond players saying gg get good its not ranked doesnt matter. Boosting is boosting either if its just normals since the winner team gets more ip and the possiblity of chests as well. riot needs to put in the matchmaking system they use for ranked in normals. Make it where unranked bronze and silver players possibly up to gold 5 can play with each other and have gold 4 and beyond only play within those ranks.
