there's one or two that are better, but you get the point.
you can punish 6C on whiff, block or ib with just about anything you want to, lol. if you're getting hit by 6C you've got other things to worry about.
rachel is hella hard for hakumen in ct. you can zone my ass out all day long, you can beat any of my jump ins with your 6A (unless i j.D it on reaction, which is next to useless in this game anyways, lol), and you can rush me down so well that even if i ib your blahlblahblah j.2C blockstrings i rarely have the opportunity to get a 1 frame counter out (that's right, even when i'm +5, i'm still at - frames).
if you're losing as rachel it means one of three things:
1. you need to learn how to block
2. you are wasting your wind meter
3. you aren't taking control of the match
blocking hakumen on the ground is easy. in the air? just look out for hotaru and stay out of air throw range.
the other two are simply not knowing how to play rachel.
