Lot of people complaining about paid online without knowing much about it, and also claiming it's not worth it because Nintendo has poor online.
Servers cost money, bandwidth costs money, service costs money, people need to stop expecting things to be free and it's kind of annoying seeing all the negativity about this when they don't even have any details on things like pricing or how online is.
People wonder why Nintendo online hasn't always been the best in the past and that's because they offered it free, don't expect to get better online and not have to pay for it.
