How am I getting teams in silver where people don't even understand the basic games.

First off, I've been on a terrible losing streak and still try my best.

I try my best but in silver I come across teammates who do not understand how Darius works and rush straight in to hit him in the face over and over again.

I get top lane tanks who split push all game.

I get supports who don't even use their CC or ultimates in teamfights.

ADCs are a while different story and have literally nothing going for them.

Last match I had a game where this guy counter picks the top lane Darius by picking a Garen into him (of course). Totally new player who walks upto him and feeds 3+ kills trying to 1v1 him in his own minion wave. Fine I go top as Katarina, gank his lane, and get him a kill or two. He's back at the same tactic despite me typing out how Darius works.

Next in the same match I have a Fiddlesticks who walks into Darius's range and feeds him. A Sivir who constantly loses a 1v1 to a fucking Darius who is neither carrying Phase Rush or Ghost. How the fuck can you be so bad?

I am constantly getting such players who do not even understand which level their ultimates unlock at and try to 1v1 a full HP Aatrox who just got a kill while at 1/2 HP themselves. I've got players constantly who ignore the top lane, gank bot all match because dragon but then never take a single dragon.

Since when did the game become so shit where people don't even understand that they're supposed to use their CC in teamfights?

This is silver we're talking about. There are two entire ranks below it! There's bronze and fucking Iron. As a Silver player I expect my teammates to have at the very least an understanding of the basic mechanics which even a braindead monkey would.

Why would a Lux not press Q in a teamfight ever, and why would you find a Garen run into a team of 3 people solo while a level behind and think he could 100-0 them through his spins? I expect such monkeys in Iron and maybe low bronze but when did people who literally do not even know common champion matchups such as how Darius and Lux work start to remain in silver with no threat of dropping down?

Literally no other Moba I have played has such bad matchmaking.
