My first game of AL was great, and I was paired with a talkative and helpful teammate and one silent but cooperative one. After that it ranged between silence (Comms and text) to outright hostile. I like the tagging system and appreciate not everyone can voice Comms, but everyone can type hi. I went back to OW.
Not to say OW is without problems, obviously. Not related to OP is throwing and smurfing. I was in a Stay As Team group that got dumped into a large group of smurfs. They let us cap and win and didn't even contest, but would occasionally just mess with us to show off their mechanical skill. Most of them could have 1v6'd us. Most of our team reported them, but it was just really disappointing.
OW definitely has problems, I just find them less than other games.
What region were you playing in, and have you tried others? I get that ping might be an issue, speed of light being uncooperative and all, but I'd be curious to know your experience based on region and what times you play.
