I think in brief summary, Kitana players can really be happier after this patch. U2 change really deleted one of her most glaring issues and now skill to flawless block things can be finally utilized.
B14 being mid, mid mid is really nice change as well. Not only we can now allow ourselves to whiff first hit and not get D2 KB (lol), but as
@DarksydeDash mentioned, B14 is now better meaty string, because she can catch ppl on jump and still be able to convert.
Jumping nerfs are not really that big for her, since she has 2 really good jump attacks. PPL won't be really able to flawless block both J2 and J3 at the same time I think and her J2 is still as good as it was.
Fan-fare can for sure call this patch nice for her. She can convert from U2 into nice damage. PPL are talking much about J3 OS and special cancels that won't come out on block, but will on hit. She can do it as well with butt attack in this variation. Just do J3 into slight delay BF3 and it will work.
Also maybe useless fact, but she seems to be the only character that can bypass this new rule with her float. If she does jump attack into float into J3 then she will be able to cancel into ground special on block. I don't know if it's bug or intentional, but that's how it looks now.
Both changes - B14 and U2 - makes now Highborn even more stupid and it's safe to assume that gap between Highborn and 2 other variations just keeps spreading. B14 being mid mid mid deletes her issue she had that some characters could make B14 into razors punishable. From what I tested only Cassie and Johnny can still make 2nd razor whiff, but it's not consistent. It seems like some sort of breathing hitbox issue - lol.
Fearless seems to pick shorter part of the stick with this patch. It's basically the same Fearless in new jump meta with new B14 and better U2.
