I have no opinion about seeing her H+K getting nerfed a bit. If people(especially some non-Kasumi players) can stop whinning by nerfing that move, then I'm okay with it.
I agree with you on her highest damage output juggle. You think the added turnaround stun to 3KK will increase 3K's usefulness in stun? I personally dislike 3K because most followps to it whiff unless you are at a wall.
I tend to use 6K to extend stun instead of 3K but with the added turnaround stun to 3KK it may force the opponent to hold a bit more so we can capitalize of the whiffed hold. By the way do you have Skype?
KK7K6P+K -> 9PK6P+K -> KK
As for 236P, it's slow and has long recovery so I doubt if it can be used as a good relauncher.
