I think people are looking at the run mechanic and thinking 'obvious get in', but there plenty of times in the Fatal 8 matches that Sonic Fox ran from half or 3/4 screen and pressed buttons and the opponent didn't do anything. Like Injustice with dashing, if you're letting people run into your face and press buttons then there is problem with you, not the run mechanic. I'm not a fan of safe 50/50 mixups, but regarding the idea that it's 'Knockdown + Run In = Free pressure', I'm confident that people let a lot of things slip in regards to punishing run ins on knockdowns. Obviously some setups will work better than others e.g. EB's tackle hard knockdown looks sucky to deal with, but we definitely didn't see the full extend of counter options utilised. For instance, there were no wake up back dashes used to whiff punish run cancels.
People saying that zoning legit looks dead simply have no idea how the meta game will work out, and the reality is that we saw 6 aggressive and rush-down oriented players playing in the tournament, not to mention that unfamiliarity favours offense. Looking back at the games, it's very easy to see where defensive strategies will develop and how the game will slow down from what we've seen.
Regarding Sonicfox, yes he used a mixup heavy character, but his understanding of the game was visibly so much better than the rest of them. His footsies were far better, his reads were fantastic and was adopting strategies to beat out peoples inclination to poke. He clearly used a great character but he was by far the best player in the tournament.
