IDK if you know but Nightwing is my new main. I've played Wonder_Chef's Supes and others with him. Originally I tried it out from Supes perspective. It's obviously not a free win, but he definitely kan deal with him. I've used other characters like Arrow who's fastest move is their 7 frame D1's so they lose the trade with F2 after F23 Breath and whose back dash, even when timed korrectly, leaves him forced to block the 3. They are left with only one option (and having only one baitable option is never good), MB B3/F3.Nightwing has a harder time with supes than you might think. But it's not the matchup that I am concerned about. I have no problem playing hard matchups.
It just concerns me that if the trend continues, everyone is going to go to those "Special Characters".
Nightwing kan deal with Supes zoning as well, making him think or be forced to kome in.
We sort of have to use those characters at this point in the game. That's why I switched to Nightwing. He's the funnest character up there..
