To be fair, She never had to actually fight anyone, during her time she just wrecked house and nno one could stop her. This is literally her first fight against other people using ninjustu.
But the Kikashi thing is annoying, I'm guessing Obito soul resides in Kikashi, which is turing this manga into some Disney level type shit.
Though this does confirm, and I said this a long time ago in some thread somewhere. If Kakashi had both of Obito's eyes he would be OP, not even Madara could stop.
