So when I can actually connect to a player, the matches were mostly smooth today (one match had constant slight input lag, another had one lag spike). However, for the past 10 minutes, I can't connect to anyone in any mode. I can still spectate, but not letting me into matches. Tried restarting everything, etc, no change in my internet connection either. Still feels better than Brawl at the moment, though, but wish there was a way to address the inconsistency. Also no way to check player connection ahead of time.
Edit: I'm also terrible at competitive Smash. Won only one match in For Glory out of ten, and many weren't even close. Back to XIV for me.
