I don't agree much. It's true that there are several grapplers in the game but none of them are alike in hardcore play and I honestly don't find Rachel shitty at all... even post-patch.
Thats my point, the other grapplers fill out pretty much every role/playstyle.
Defensive/Evasion/advanced counters/parries- Bayman
Offense/Guardbreak pressure/Environmental use- Leon
Mixups/Great Crushes//blonde with enormous tits- Tina
Ground game pressure/Vortex shenanigans/- Bass
The above four also have extremely high throw damage output, chain grabs and can ground grapple with guaranteed setups for them to make up for their slower speed where Rachel has none of that.
Then throw in hybrid characters like Busa, Lisa, and Mila who have fast attacks and good mixups to go along with their grapple game and Rachel looks even more out of place with nothing that stands out for her. obviously Im not saying shes complete shit and can never win but she is indeed the worst of the grapplers overall due to not excelling at any category that the other grapplers have her beat in
