Pub games are unpleasant. People talk shit, leave mics open, leave music playing over the mic, shout whenever they want to say anything, make stupid demands. That doesn't even include how frequently people are abusive.

I don't play multiplayer games much anymore. But even games that need heavy teamwork aren't worth keeping voice chat on for (e.g. Apex Legends).

The only exception would be when I played with members of a closed community with full pre-made teams.
