Ahh, this thread reminds me of the time when Sasuke was confirmed to surpass Madara. As a recurring theme in all of fiction, talent trumps over experience/hard work/whatever most of the time.
Now back on topic, I would like to understand how Camille dumpstering some fodder characters accounts to more than Fiora gaining respect from an actually developed character who is so insanely good that he had to have his weapons away. I don't care about silly Spiderman villain-style augmentations. The fact of the matter is that it is not possible to compare the two in terms of feats when only one of them has a fair bit of source material. But since you did mention that this is an 1v1 in an arena and Fiora already has knowledge of her presence is pretty much a curbstomp, or at most a mid-difficulty. And the fact that she is super-human accounts to nothing at all in an universe where a half-dead Irelia is brought back to life and proceeds to murder tons of Noxian military troops effortlessly. They are all superhuman. At the end of the day that is what unnamed fodder punks are for, hyping up a char but in the end they do not count. League's plot is way underdevelopped for what it could be. For all we know Synd should theoretically be the strongest of humans, but with nothing to base that off that is but a wild guess.
PS: In my initial comparison talent aka Fiora(Sasuke) is supposed to win over experience Camille(Madara). You can argue that Camille is talented too, but then again needing silly augmentations does not scream insane talent to me.
