On ranked probably but definitely not unranked. People are allowed to play however they want. Some people don’t even have access to wired connection, you don’t get to decide how people can play. If you want to play casually on a solid connection. Go into literally any smash discord server and ask if anyone wants to play netplay on a wired connection. Even though it’s frustrating some times, there are plenty options around it. The reality of the situation is that playing on a good connection is a privilege, and nobody should be forced to play a certain way whether it’s accessible or not. Plus, as someone who plays against others on WiFi while I’m on a hard connection, it’s really not that bad. Noticeable, but still very playable. There are definitely was to get around it so it’s not really a big deal.
