It goes both ways. People tend to post about negative experiences. Rarely the positive. I never said it doesn’t happen, merely state that not everyone does.
If every game that everyone plays was like you mention, every match would be 5-man premade groups. And that just isn’t the case.
I decided to test myself to see how many games I played against pre-formed teams. So, I queued solo and played somewhere between 10-15 matches:
Two matches were against fully formed 5-man premades, and I had one victory and a loss. All the other matches had assorted 2-man, 3-man and solo players. I went close to 50-50 on win rate. Surprisingly better than I usually do playing with my friends. Now, this is just my experience and a small test sample. It’s also on PS4, and maybe that makes a difference. I hear it’s the most popular platform.
I can’t speak to anyone elses experience, obviously. But if this is how it is to be a solo player, I really have nothing to complain about.
Sorry you’ve had a bad experience. I’m still very much enjoying the game. Team or not.
