Custom CC Games are way better than Ranked

Some people don't want to play in voice chats/discords/communities though and whatever their reason it's perfectly legitimate and doesn't go against "how it should be".
Whether it's being self-conscious, not speaking a language very well, privacy concerns, not being comfortable to talk to strangers on the internet, not being a people person in general, or just not wanting to talk because you can't be bothered right now. All fine.

Also, communities aren't always peaceful and dramafree. If you look at PvE raiding and statics you'll find your fair share of really questionable experiences, incl. voice-chat specific experiences. This can happen in any community, incl. pvp. So if somebody doesn't join online communities/voice chats because they personally weigh the risk of drama/weird experiences as higher or more impactful than the potential positive experiences they could make then that's up to them and also fair.
