Thankfully, it's getting CRUSHED in user reviews... which will undoubtedly happen to an even greater extent when Splatoon 2 drops.
This could be the worst thing introduced since Microsoft's original Xbox One DRM/usage policies (which is still burning them to this very day). The Switch already has a lot against it with the "painful launch" video and continuing harm the Wii U did to their reputation.
I hope they take a card from Microsoft's book and listen to their users. Using a BT headset and having party management/communication handled through the system makes SO much more sense. There's a lot of people looking for a reason to write the Switch off as another Wii U, and this could be just the ammunition they need.
