I have said it for a very long time, but public servers/matchmaking have been the single worst thing to have ever happened to online gaming, and I will die on this hill. Lootboxes, MTX, even pay-to-win is all irrelevant compared to the damage that matchmaking has done to the social structure of online multiplayer gaming. And that isn't to say that those things haven't done a lot of damage, but they're nothing compared to the damage matchmaking has caused.
