Well 1A:A is hardly a JF too. Once you got the timing right, it's kinda hard to miss the KD. 1A

A is slightly harder (because the third A has a different timing) but still really easy to do compared to real JFs (Yoshi's 4A

A:AA as an exemple).
Why are her low better? Risk / reward !
In SC4, her lows have a really good reward for a risk that is clearly smaller than in SC3:
CH 11A > 75 dmg, super TC (goes under some mids used correctly - like X's 44B ) and a really good anti step tool. Adv. on NH too.
2A+B > around 50 dmg (don't remember exactly) and a lot of characters cannot punish it with good rewarding moves because of the push back. Though it's still unsafe.
1A:A pushes back far more than in SC3, though still unsafe and it can still be seen on reaction, but it has a very good tracking (360?) and you can't always be sure to block the first low. I kinda miss the long distance RO though.
214~2K > Slightly safer than regular 2K (really hard to punish for Cassy as an exemple), it's still a good move to confuse people.
Used after a GI, 2A+B and 1AAA are really good (or 1AAA for front RO/Wallsplat), while 11A, 214~2K, 2K can be used for pressing/active defense (11A is a very good active defense move).
236 stance makes deceiptive animation and can be used to use her low.
Her low are better believe me (but they're still not good :/ Only 214~2K and 11A are really good).
Can you devellop about my tier 1 placement and about YunSung? (especially YunSung)
