well after spending all day literally spamming X non-stop (had my gaming monitor setup next to my TV) i was able to connect twice
the first time was over wifi and i was able to get in 3 matches 2 of them felt really smooth 1 was lagged to hell then i got kicked and when i was able to get in the second time i was over a wired connection, this is when cammy and birdie were added i was only able to get 1 game in over a hour of messing around in the training room..... the one game i did play was AMAZING if the netcode is this good in beta it should be great for launch!
i finally discounted myself because i couldn't find anyone to play and was getting bored of training room, and i didn't want to be one of those D-bags that trys to stay online and go AFK i know slots are limited
