I don't think they've changed anything internally about the game. Shiki's dive always did that if their sprite was behind you, and there are a lot of situations in this game where you'll be backturned but be able to block the normal direction...I'm assuming that's the case there. I haven't noticed their sprite being backwards when I do the reset midscreen, but that's probably the case...
Some characters' throws in the corner do force them to get up backwards, part of why Kim is so good. He's better than Big or Marco, really. Big's damage was never really a problem...more how he has the best defensive game among the cast. cr.A and lariat shut down the offense of a lof of characters...as with all things, there's a way around it though.
I'll have to look into the Shiki thing though. I wouldn't mess with cr.A > cr.D > dash stab btw, two hit cr.D alone is enough to confirm usually, about as fast (maybe faster? the A is kinda slow), probably more damage too. That, cr.A > close B > far D > dash stab, or close D > one hit close C > dash move.
You have a pretty decent amount of time to see if dash stab hits before you press C for the flip launcher too. I can usually just confirm off that itself. If they're a good player and start trying to GCFS the stab on block, you can use the super cancel to punish their punish attempt ;p ...if they're not GCFSing or AB stepping through them, you can basically spam the crack shoot overhead special and dash stab all day.
Which also reminds me...the guy asking above about escaping pressure without "meter", well, are you talking about stepping or supers? I could read that as "you can't escape without having a super stocked", which isn't really true, so I wanted to make sure you knew about AB steps/GCFS. They do use meter, but not very much and as said earlier, meter is given to you in this game for doing pretty much nothing.
