gaining points in ranked

gonna call out that dunkey said this in a video a long time ago which is still not implemented into the game which is a FUCKING GENIUS IDEA is that if you get a lot of assists kills farm help take tower dragon baron ect you know doing good in the game and yet some how end up losing the game i should not lose no way near close enough the points i'm losing but maybe even gain points even if i did end up losing a game cause i had this consistent problem where i get bad team mates who fucks me over even when i play well and trying to win my damn hardest and then ofc i end up just losing the game and lose a lot of point kicking me down the ladder and i'm just siting thinking man thx riot for your amazing system LIKE COME ON GUYS this is not a unfair or unbalanced way what so ever i srsly don't care how hard you guys need to work to get something like this into the game but DO IT JUST DO IT i should not be punished when i lose a game when i did well its complety unfair i should not be punished for my team mates misstakes and just awfull game play
