@Spam286:
She said her mother told her that hurting people was bad when she was a kid and you're reading an awful lot into that to say it defines her as a person. Her fighting style is geared towards coliseum fighting and it's served her fine up until now. She's expressed a desire to take out Doflamingo which suggests she's not against harming people if she needs to and we don't know what she's capable of when push comes to shove because push hasn't come to shove yet. She didn't take out a named character, but then the only people that did that were Orlumbus and Hakuba. Cavendish didn't, and neither did anybody else in the block.
'Seemingly unsolvable' is our key disagreement here. Until Hakuba there was nothing to indicate who was going to win block D except for our own prejudices. As far as I'm concerned, Rebecca still could have won. Once Hakuba appeared he himself was the problem, and Rebecca's avoiding being taken out was a result of her amply foreshadowed speed, so not a deus ex machina.
Cavendish and Hakuba are the same person, what's so hard to grasp about this. I think you need to reread the defninition of deus ex machina again. It was a convenient intervention that came out of nowhere. And if you're delusional enough to think Rebecca would've won anyway without Hakuba, well then I think we're done here.
So I did a double-check and as far as I can tell your 'in awe' refers to the single panel immediately after Luffy one-shots Hajrudin. She expresses surprise that Luffy would be that strong. Cavendish meanwhile says 'of course' or something similar. It's not the level of strength that surprises her, but the person it's coming from. Cavendish isn't surprised because he knows Luffy by reputation. He expected that level of strength out of him, while Rebecca didn't.
Do you seriously think Cavendish would have a shocked expression on his face if it were, say, Jean Ango that took out the giant? No. Because it's not a feat of strength that he'd find impressive. Rebecca, on the other hand, would've been in awe regardless.
The fact that it's the same tournament doesn't mean squat. You can't make a comparison based on fodder and the named characters all have wildly variable stats. Unless two people fight each other or the same single enemy there's little means of comparing them, and even then circumstances have to be accounted for too. We don't actually see the speed at which the fighting occurs because manga doesn't move, so what we see is what Oda wants to show us at the pace that conveys what he wishes to convey. Sometimes three panels represent more time passing in-universe than an entire chapter.
So Cavendish is a total beast who nevertheless failed to take out any named characters in his block, something you earlier in this very same post tried to use as evidence against Rebecca? And when Bastille says Cavendish is good with a sword that means something but when Sabo says Rebecca is fast that's meaningless? Come on. At least be consistent.
Again, there was no reason to display Cavendish's power, we've seen plenty of it with his short skirmishes against Chinjao and Luffy (the latter whom pretty much toyed with Rebecca), Oda saved the name characters to be fodderized by Hakuba to show Cavendish is even more of a beast in his "Mr Hyde" form. Sabo says that Rebecca's speed "wasn't solely based on luck" implying a combination of luck and skill, so I don't see how this suddenly makes her some "speed prodigy".
You still don't know that she's going to be beaten, and she definitely doesn't know that she's going to be beaten, so until that actually happens you are wrong. And since the phrase comes from a real life battle in which the victor suffered such great losses that it wasn't worth it, you are still using it wrong. Rebecca hasn't lost anything. Even if she loses in the final she won't have lost anything.
Again, you're trying to dodge the original point of my argument: that the victory serves no purpose because we as an audience know that Rebecca has not gotten anywhere closer to her goal, nor has she grown as a character. Hence, bad writing. Again, I'd assume getting beaten half to death by Jesus Burgess would be considered "losing something", and if for whatever reason she escapes the round unscathed because Sabo decided to bend over for her, it's again unbelievable writing.
