Not that this post is intended to be a lot of help, but I guess I could get things on the topic.
Now I'm talking about good Rachels, not the crappy poser ones who don't use their wind properly.
Whenever Taokaka tries to get in on Rachel, she will purposely user her wind to keep you away, shooting a staff and eventually electrocuting you one way or another from a distance and using that to segway into a combo.
My main issue is her wind; because whenever I fight a good Rachel I can never get in. They will constantly keep me out of range with the wind and unfortunately Taokaka's drive just doesn't seem to do the trick. The worst part, is you'll eventually get close through pure will power, and Rachel has her special up, which never ends well. On top of that, Rachel seems to have a toolkit of ways to interrupt tao from close and get you where she wants you.
