I can vouch for that. My senseis Render and Panic don't even play anymore :-/ Pretty much anyone I wanna play is never on, this online tournament thing I'm doing Saturday is basically all I have atm
Although I wouldn't call it dead, it's still fresh imo, people just need to take the initiative to play it, even if I'm not playing online a certain day, I at least practice or do a arcade run to stay flexible with whatever character I'm using
