normal games are unplayable

the balance of good players and bad players is so swayed it makes the game a blow out every time. i either go 30-0 cuz they suck or 0-30 cuz my teammates arent even concidered playing. i have 0-7 kennen support in team builder my gold 3 nasus fed an unranked feeding every game warwick with smite top their nunu gold 1 jungler is 4-1-14 cuz he kills my silver 2 r%%%%%ed jax all game while im destroying a karthus mid. like i should be only playing with plat 5 and above players yet im getting silver/gold r%%%%%s on my teams vs unranked/gold 1's while i get silver 2 feeders i dont get why matchmaking in normals is so bad but its litearlly unplayable its not fun in the slightest. gold 1 nunu's try harding vs my silver/bronze teammates while i play a first time champ is really fun
