She's pretty easy to use but isn't exactly a win button. The only high level Rachel main is Gehaktbal (though he uses Zack quite a bit too).
He stopped maining Zack when they messed with his favorite force tech setup. So yeah, there's still a top player who mains Rachel.
Oh yeah there is him, but from what I heard from a source he is trying to pick up a stronger character because he realizes she isn't a bread winner.
That's what I heard, but i mean if not cool. I love his Rachel. But yeah she is preeettyyyy mid tier imo. Not cutting it when you get to the upper levels of play.
He has always picked up multiple characters but he thinks Rachel is very good so I don't think he'll drop her soon.
