Why shouldn't people complain about a system that's missing features that it realistically should have?

You seem to forget that both the Xbox One and PS4 had their time where people complained about the features they were missing. The Switch is just launching, and we're just learning about the system, so that's were the focus is obviously going to be.

Bet with Adamblaziken:

I bet that on launch the Nintendo Switch will have no built in in-game voice chat. He bets that it will. The winner gets six months of avatar control over the other user.
