I give it a 7-3. On the rare occasion that I beat a Superman, it's clear that it's because I was MUCH better than him.
I was playing with my GF's bro online, we did a ranked match and we saw a dude who had 1100 wins and 200 losses. So her bro gave me the sticks because he didn't want to play him.
He picked Superman, I picked Nightwing.
For some reason, I always prepare to block F23 so I won't get punished right away. I thought he was going to be a good Superman player.
Instead, he went full screen to the left, Laser spamming madness. When I got close, he did a good job in surprising with that BF3 move Superman does with the MB that sends you back full screen for Supes convinience.
Well, I got raped the first round, but the 2nd round I finally got him the corner and man it was a beat down.
Cross over J3's, MB Flip kicks, throws before he could do a wake up. I took his whole first bar without him touching me.
But then I drop the combo that would of ended the fight. He went back full screen and began chipping my life away with the laser spam. So I lost.
I wasn't mad at him. You gotta do what you gotta do to win. It's always a struggle for NW against Superman and this time I didn't use staff because mobility is limited and he was very dedicated to spamming the lasers...I didn't play so great either.
The struggle continues, but we love it because it can only make us better players.
