In my experience it displaced Mumble and Teamspeak only for casual gaming. If your group is strict enough about muting/kicking people who refuse to fix their mic settings, Mumble or Teamspeak is generally better -- better quality, local volume adjustments, less resource hungry, open mic not being the default, etc. Think tryhard esport players, or just people with old hardware (probably 90% of CSGO players )).

For my group this wasn't about mic settings but mumble being bad out of the box. Maybe because we didn't pay for the servers and used a free something, maybe because of bad luck, I don't know, but every experience we had with mumble was terrible. For teamspeak, while the voice part is great, the message part is (or was at least in ~2016) lacking compared to discord. We were coming from skype/twitter which had better…

Yeah, the text chat is just crap. I think most people use a separate thing for that, probably Steam in the PC gaming use case.

This then also means a well defined server API without undocumented behaviour that individual implementations depend on. I stand by my assertion that the good scaling and separable builds is a sign of good architecture.

Isn't a non-leaky abstraction a given too? All these requirements are like saying "having a good experience using this app requires an app that doesn't crash all the time". Well, duh?

Life would be a lot easier if good engineering practices everywhere were a given.
