What's up with crazy duos and 20 bombs just playing terribly?

I have almost never witnessed a great 20 bomb player in solo matchmaking. In my experience they are usually just absolutely going sonic through places, and their ability doesn't seem to carry them all that far in solo's. They seemingly expect to drop anywhere and just cruise through people. In my time the average 20 bomb is literally a 500 damage 1 kill player lol. It doesn't make sense. I always expected these guys to be able to work with any team and just crush people with good tactics and strategy. But it doesn't seem realized really almost ever in solo play.

And then the duos as well. I get duos, who may or may not be good, who again just cruise around the map, get angry if you drop where they don't want to, and then expect you to magically know exactly what they want and where they want to go. Follow or get lost basically. And when they die OH BOY get ready to be blamed for everything lol. This is almost my experience universally in this game with duos.

I've honestly grown tired of it. I now mock these people as they are down and just cash out before the team is gone. It's not worth the struggle. Whether it's because they need a full stack against randoms, operating in tandem, or they just aren't very good alone, these people seem to get by with just pure luck. The minute to minute decisions a lot of these people make as solos are just bone dead logic if what you are trying to do is win games. If you are going for kills, well I can't say that seems to be working for any of these people either. As somebody with a 15% winrate in solo's, and around a 2 KDR, I don't really care about getting 15 kills, nor am I willing to sacrifice the best games of my short day playing this game to try and get loads of kills. If they come well great. If they don't I am still going for the win as I don't play this game all day.
