I really feel like the matchmaking is tighter since OW1. I play in groups a lot with a mixed-rank group of friends, and it always felt in OW1 like me (very high rank) being in the group would wreck the match for them, because we’d all get matched against people of my level.
In OW2, it actually matches by role, so what happens now is that I have a counterpart on the other team in my role that’s my level, and my friends are also playing against people of their level in their role. That feels better to me. My plat tank buddy can actually tank with me in the lobby without having to go against a GM tank that’s going to roll him.
The same people who run to all corners of the map to 1v5 everything in 5v5, just repeat the process in 6v6. That’s my observation anyhow, as a solo-queue support player.
The team that has the most people sticking together, where at least one tank and one support and a dps are working together, wins. The matches are just horrendous blowouts though. Once one team stumbles it seems tough for them to reverse the tide.
The only sad upside (maybe), is that I see so many backfills, that it seems to knock out the challenges for games played pretty quickly.
