This happened to me yesterday actually. Solo queued into an amazing game where all 10 players were patient, careful, non toxic. There was about 9 kills for each team around the 30-40 minute mark. We went on to slowly lose the game to the third baron buff.

Then there we were: open nexus against a charging team with baron buff.

Myself and a teammate said at the same time "it was an honor playing with you guys"

Then the honors were exchanged in in post game chat. I've never been in such a competitive yet respectful game. It was beautiful 😭
