Why is convenience and quick game-play better?

Is that a product of long travel times though? I question because even running mythics or normal/hard raids no one really talked in legion (last i played) i know the travel times weren’t as long but atleast in mythic+ the cost of not getting to know someone was alot higher then even vanilla. I think i only added 2 people to my friends list in legion but i only played through end of nighthold.
