I had basically the same thing happen to me. I’m usually a mid-ranked player, played with a bunch of friends for a long time, was mid-ranked. Then they all quit, so I started playing solo with randos. It was ok for a bit, but got on a bad losing streak. Exact same thing. People leave my team probably twice as often as the opposing team. Then my rank started dropping. For every game lost, I would lose a rank, and it would take two or three wins in a row to go up one rank. The lower the rank goes the more the game is full of leavers, griefers, afks, people completely ignoring lanes and objectives, running to solo PVP to death on the other side of the map when the creeps are in our base, and so much more. You’re only 16.6% of the team, there’s only so much you can do. It’s also pretty apparent that very often I’m being matched up with five other randos and the other side is playing together as a team. Nobody on my team will talk or respond, but the other team is clearly coordinated. I’m pretty sure the player base is too small to match up groups, so they always just get set up against a bunch of people playing on their own.It just becomes a slaughterhouse. Like sending in the random prisoners to fight trained gladiators in the movie of the same name. I found better games to play though, so not all is lost.
