Hard to say, between games like LoL, PUBG, and Overwatch. Generally speaking, newer, or highly populated PvP games have such a childish, awful community that makes it mandatory to auto-mute everybody.
A combination of PvP tryhards, frequent cheating, and random matchmaking destroys any chance a friendly community could have had. You never saw anything close to this bad back when you used to have to connect to dedicated servers for games. AvP2, Quake, Unreal Tournament, those games had FAR better communities, because you typically played with the same pool of people on the servers. You obviously had some dickheads, but nowhere close to the sheet volume you do now. Hell, the fact that you had to do some work to get into online matches helped weed out the little kids - something that these shitty random queues don't do.
I have a signature. Apparently this is important, but I still don't have my secret cool kid decoder ring yet.
