I didn’t make this but I remember a sparring partner being baffled that he didn’t get to punish an EX-DS (Blocked) with SUPER and went to hit his frame-data (Included in the end of the movie). We assume he just did the motion a frame too late because apparantly even that can be punished on block.
In previous matches he made a point of just outright scaring me from using any special once he had SUPER which he would save for the entire match while playing keepaway Chun. Chun has a blatant advantage over Balrog - It’s not even entirely down to Super, it’s her having typically better normals, better at playing keepaway with an advantage and more mixup potential. Only thing Rog has in his favour is Chun’s low healthpool.
But yes, Chun with SUPER will pretty much disuade every Balrog with a braincell into using anything, even his crouching roundhouse (Sweep) can be SUPER’d on Block for flip-sake, which means Rog loses mostly all hope of chip damage from specials and EX specials, nevermind a big chunk of his footsie game, if the Chun is any good at all.
