Okay, this is the last time I'm replying because I'm sleepy and because it's kind of obvious that none of us here will change their minds despite the evidence the other provides.

Your argument doesn't make much sense. Minerva takes on both of them by utilizing her Magic which allows her to separate them. It would count as her fighting them both at once, because she separated them, the one of the two did not magically disappeared. It's her way of fighting because her Magic allows her to. Not allowing her to do that would mean that she would fight handicapped. And even then, her feats do point towards her taking them both at once(see images above I posted), like she did with Kagura and Erza (who are probably stronger or at the same level with Natsu and Gajeel) just saying.

I doubt such thing as selective intelligence exists; if she can think before a fight, she can think in a fight. Except if she gets really nervous, which she doesn't.

Well, of course that's my opinion. Her somehow being unable to negate Natsu and Gajeel's attacks is also your opinion. That's what we do, exchange opinions :P
