Full PoF Natsu and serious Gajeel's feats are superior than non serious (sheathed) Kagura and Pre-SO Erza's (with 2 simple swords and without any armor) feats easily lol. That much is pretty clear.

Natsu smacked both DF Sting and DF Rogue around easily. I heavily doubt Pre-SO Erza can do the same seeing as DF Sting alone took attacks from Semi-PoF Natsu and non serious Gajeel without even having a scratch, and made them look like noobs (something x784 Jellal or x784 Laxus tiers would usually do). And the two of them (x791 Semi-PoF Natsu and non serious x791 Gajeel) are easily stronger than their serious x784 versions. Which means Full PoF and a serious Gajeel > Pre-SO Erza and non serious Kagura.

Saying Minerva can teleport one (or both) of them to another dimension and have nothing go wrong is an example of No Limits Fallacy. Besides, like I said, Minerva would have her hands full with just one of them. She's not taking on two of them at once.

During a fight, you have to pay attention to the opponent in front of you. There's pressure. Outside of a fight, there's no pressure. Big difference. Minerva has yet to use her intelligence in a fight she didn't prepare and plan properly for. That's why she fought SO Erza like she did during Tartaros arc. She had no hostages, after all.

I said she can't react to both of them constantly and relentlessly attacking her at close range combat. Both of them are very agile themselves. They are Dragon Slayers. Close range combat is their forte. They are gonna hit her with their attacks pretty often.
