Christie doesn't have force techs / pseudo force techs in this game to my knowledge. She also doesn't do as much damage as Rachel. TBH if everyone still had force techs no one would say much about Rachel.
I hate Christie more than I hate Rachel. At least Rachel is slow as balls and can be countered easily. If they nerfed the speed in which her follow up moves execute out of her JAX stance, she'd be a little more fair. A SS that ducks Mid tracking moves is bullshit.
Jak2k is no stun more ~ Jak1k6k is now crazy unsafe on high guard in vanilla this move was so quick you could only try to hold the mid kick and it was a deep stun now it works only in neutral in combo with 6k jak1k6k or as counter hit. Jak1kk was a crazy awesome tournaround stun on neutral hit it was a low and high hit.
