I see where you are coming from about your disagreement I completely agree but if you noticed I stated in above post, that I was mostly going to be talking about Jin.
214A wallbounce in INSTRUMENTAL in doing beastly corner damage.
I have yet to see the use of 214A wallbounce I have tried to implement it in my play style but I really do not see where the bounce comes into play.
While I agree the 6C nerf is pretty bad, the ability to dash 5C after Sekkajin is huge. It leads into (for me at least) combos which deal more damage and are more fun than their CS2 counterparts. 6C works well in a lot of ways still too, it just isn't as godlike.
I also agree with you on that part I described how even though they took away 6C->5C they decided to add/or teach you that you could do it in CS but to less extent since his 6C overshadowed any of his other combos. But the guide you have described I have yet to look that over but i'm sure once I do it should help me out a lot. The part I have the most disappointment in is the fact all of Jin's attacks are easy to block and counter. Yesterday I played against a Makoto and just got my backside handed to me she completely dodge or countered most of my combos. That is the most complaint I have as I described about 6C they made it easier to dodge or interrupt an example is in arcade. Where unlimited Ragna just used inferno divider and just screwed my combo. I mean he would be in the basic combo of 2B->5B->6C and just completely interrupt it.
