2. You can't quickly "wash" off oil by standing in the rain. You know that.
Dunking into one of the plentiful pools around on the other hand... it was removed by a water jutsu pretty easily, after all.
But let's not forget something else: Having your jutsu restricted does not take you out of a fight.
Orochimaru with no arms. Jiraiya with little chakra due to Tsunade's poison.
There's a huge difference between suffering a major disadvantage and being taken out.
3. Taijutsu against Jiraiya? That's very suicidal. I doubt few could tango with him in just his base form.4. It's still silly and absurd. She bowed out. Jiraiya commented on it. She was defeated. It's absurd that you're giving her far more credit than is necessary.
He had a major advantage and would've won if they kept fighting, and she had a partner to swap places with, so it was the smart thing to do. That is absolutely not the same thing as her already being out.
Someone with good battle smarts like Minato would quickly deduce the "oil" weakness, as well. She just doesn't stack up against other S class ninja UNLESS she has prepared a shit load of explosive tags.
And all the S-class ninja without oil? I.e. all of them?
That's like saying Deidara's not an S-class because any other S-class ninja would figure out his electric weakness and defeat him. It's a pointless thing to say as most S-class don't have enough lightning jutsu to counteract his advantages... and it definitely doesn't change that having a weakness to a specific thing doesn't necessarily lower your rank. The more narrow and specific weakness, the less likely it does. At least lightning is common.
Conversely, a more physical based S-class ninja is more screwed against her than normal no matter how smart they are, so she similarly has a compensating advantage.
And she does have explosive tags normally, you realize. Just not billions- and with billions, she could take down most S+ ninja, let alone S. Let's see Onoki try and dust away that many, or Muu invisible his way out of that one.
Also she could have paper-clones already active, paper already deployed, and so on.... it's not an instant "I-win" by any means. An A-rank ninja with oil could still get their butts kicked by her.
5. Why do I need to prove anything, at all? It's already been proven: she gets owned by a decent S class ninja. She's an A+ without much prep.
Way to ignore her other fight, or how her capabilities would actually stack up to most foes. You're glossing over everything but the oil for some odd reason.
With prep, she's pretty much S+.
With a shitload of prep time, she would still lose to most S class.
With preptime, she almost killed an S+ twice, the first time without the mega-prep jutsu. Most S class would be dead multiple times over against what she did.
She's been in two fights. One she backed off, the other she did more damage than Minato did against the same opponent.
Yamato could easily cover himself up with that wood barrier. Minato could port out of there. Should I go on?
She'd blow through a wood barrier by Yamato with tags. Conversely, what's he going to do to her? His offense is largely physical, she can scatter around it then hit him. Fill the air with paper so he has to turtle up and make hit hard to fight back. Use a few hundred tags to blow through his defense then get him.
I don't see him standing much of a chance at all personally.
Minato could, but Minato can beat just about anyone. Even then, she can fill so much of the battlefield with paper that it'd be trickier for him than most foes.
6. Would not the water chasm feat require a lake of water to use? I think it would. Or are you implying something else?
Nope. It's just a whole lot of papers. Konan did it at a lake there, but Konan doesn't have water jutsu. That's just where she happened to use the jutsu. Why would it require a lake?
7. Here's the kicker: I concede everything because she's supposed to be an S-Class ninja. I was reading back on the chapters a few days ago and it mentioned something about her and Nagato being part of the "S-Class" missing nin group or something. I don't feel like reading back and finding it as I really don't remember...but I know it was between chapters 470 to present (yes, I'm serious).
But you should be conceding based on her shown, S-class level power.
You're treating like a moderate weakness to jutsu that is extremely rare is enough to bump off a whole letter grade when all of two ninja have it, both of whom could beat the wide majority of the S-classes anyway.
