Jumping HK starts up in what, 13f, is her momentum altering air move, retains horizontal momentum, WAS overhead, can crossup from iad and hits crouching (iad jhk is 4+5+13, and done usually from positions where she can be up to +8 (cr.LP)) and deals 28 hitstun. Its not farfetched to say it was great, and it losing overhead properties from IAD (anyone confirm) doesn't really break her gameplan to me. Local resident WingZero has been doing just fine with the changes, so have severin, duckator, worldjem and uzu?
I don't think its harsh so much as you're reliant on that move. The rest of the nerfs are a small drop in the big picture-- none of these changes ruin anti-air on point, nor do they eliminate her ability to be dominant up close. None of these changes keep you from doing crossups and none of these changes ruin Updo into Gregor. They certainly don't get rid of cr.LP into Cr.Lk, a Throw, delayed cr.HK, cr.MK, or IAD j.HK, IAD throw into the previous or block...
I'm personally not seeing how this destroys the character or is HARSH. Midscreen conversion from throw > Ringlet gives you a confirm anywhere. A CONFIRM anywhere leads to you being close to your opponent, where your character aims to be, and generally excels....
Edit: in the long run, this experiment fixes a slew of bugs (Filia jumping normal anchors were all improperly offset), makes j.HK less of an all-in-one tool, and in exchange gives her a buff that makes her a threat fullscreen if she makes a read. That's really not a bad deal overall! The "everyone should probably have tools revised" arguments going to need more ammunition to me, but I'm sure there's stuff I'm overlooking!
Edit2: its also a good idea to ping mikez why j.hk nerfs were a good idea-- that car rude was very informative!!
My reaction is at the idea of being shocked about these changes, not a specific person! You're free to dislike these changes. I'm just curious about implying the changes are factually bad for her.
