Why cant riot answer why I get so shafted every game?

Playing pre 30 for fun and my team is just getting straight anal pounded. I look it up plat 2 gold 2 silver something. My team? lvl 26, lvl 5. silver player.

2x I try to play and get 0-10 teammates. This is exactly why I stopped playing this shitty game and play competitive smash instead because riot cant make a fair balanced game and instead make it over the top broken as well as destroying the game over the years. If you want a real competitive game instead of this game where you arent rewarded for being better play super smash bros melee. Not only do you not have to deal with autist teammates that riot gives you the game actually rewards you for being better!
