I recently made a video regarding my personal opinion on voice chat but I'll give the textual version here.
I understand that Nintendo wanted to take steps to prevent online bullying to avoid toxicity, but I think there should have been optional voice chat feature. To me the biggest issue with not having voice chat is the lack of communication between the community in games. Folks in game can't create and develop spontaneous teams or friendships within a match. All that effort must be done outside of the game (forums, streams, etc). This may seem petty or casual, but if we want a community to grow strong and together, I think a way to talk among one another in game as potential strangers-turned-friends is important.
However it has been stated that it is impossible to add voice chat at this point. So hopefully the content creation scene, streaming scene, and awesome forums such as this we can grow a passionate and awesome fan base for the game so it can be everything we want it to and more.
