I don't have issues with people replying about it, i'm just saying that i've already made my point about it and give my thoughts about it (like i said i was mostly replying to Ave comment) , so i don't want to repeat myself about it especially in this 40 °C.
Stay healthy, man--I hear it's brutal there this summer.
Or they discovered that she lacked some another butt moves

most people seem to be okay with this ( but yeah , please no big rose hearts)
It's a mixed bag, really. This aspect of her moveset started being very grounded and realistic, because in SCII and SCIII, they weren't butt thrusts, they were hip-checks (
as I discuss here and in the subsequent posts), a very much real and practical move in martial arts and close-quarters combat. However, SCIV started a very worrying trend for this feature of her style.
And it's not just the lame as possible Critical Finisher that is somewhere between saccharine and salacious that ends with her sitting on her opponent's face (twice) with hearts flying all over the place--although admittedly that's the most obvious and terrible version of the fixation on her butt. There's also several variations of a move where she turns completely around to face away from her opponent and then rockets backward, posterior first, like a laser-guided ass missile. Now, I know not everyone has formal training in real defense arts, so this may come as a shock--but as it turns out, turning your back to an opponent and then throwing your entire weight at them, uncontrolled and unable to block, and in a manner that gives you literally the least possible ability to adjust your movement or control your fall...and your opponent is holding a sword...and the most you are going to get out of it even if it works (presumably because your opponent stopped mid-combat with their mouth agape at your sheer stupidity) is that you will bump them with the softest part of your body, with any force evenly distributed along it...and probably (if they didn't just skewer you) fall into a tangle with your adversary with your back to their torso where they can easily put you in a lock or else strike you to their heart's content, while you are absolutely incapable of defending yourself or effectively striking back...it may shock, but as it turns out, that is not a super effective combat technique!
So basically, they took the character who breathed a tiny bit of life into the realism of the franchise's combat, and became the first female character in the series not to be super cutesy (Xinagua, Seong-mina), or sexified and graceful (Ivy and Sophita) and moved her a little bit more towards being just another goofball (we've discussed just recently how at the same time they transformed her face from a lean one, with an intimidating glare to baby-fat heavy one with a dopey grin, though most people who have complained about it seem more concerned that she didn't meet their particular standard for beauty--she has a bit of a pug nose, according to some, though I think its more of a trick of the lighting on some stages--than the fact that she now looks like an enthusiastic cheerleader rather than determined fighter willing to do whatever it takes to win). And just like her sister, apparently she now has a thing for making sure some portion of her thighs come in contact with someone's face during a fight..a priority for any accomplished fighter, as we all know.
It's just a couple of moves in SCIV, and otherwise her moveset continues on the trajectory started with SCII of being really pretty brutal (she's still slamming that shield into people's teeth, or against the temples with the sword hilt on the other side, or stabbing at toes and eyeballs and midsection). So if that were the last we saw of her, I wouldn't be too worried that the butt attacks are going to be increasingly accentuated. But then there's Lost Swords, where Cassie features as the Brave Backside---sorry, Brave Swordsman. Her butt thrust moves are even more accentuated in that one and she's generally kind of more twirly like her sister--which I think is an aesthetic mistake, as I feel the fact that she tends to come especially straight at you is part of what sets her style apart from Sophitia's. Again, these moves don't overwhelm her moveset, but if you're looking for clues as to how serious PS take her character these days and what direction they are moving in with her, it might be worth skipping to 32 seconds into
her official trailer for Lost Swords. Of course, this game is a bit of a reboot, so we can cross our fingers and hope that they show more fidelity to Cassandra's earlier appearances, but this is Project Soul at the end of the day.
TLDNR: Hip checks to throw the opponent off balance = practical and awesome. Goofball attacks that throw her actual ass into the actual faces of her opponents, to give fanboys a semi, celebrated by on-screen heart emojis = please no, enough already.
