@FairyRaven -> Sting and Rogue only managed to give Natsu and Gajeel a fight because Natsu and Gajeel weren't going all out. As soon as Natsu got fully serious he murked both Sting and Rogue easily. Gajeel outran one of Laxus's lightning attacks to protect Levy. PoF Natsu is at least not far from Gajeel when it comes to speed. She also wouldn't be able to deflect their attacks 100% of the time and each attack from them would do some damage. Both of them coming at her would be anything but easy.

You all keep talking about her intelligence but what did she do with it exactly? Took hostages? I didn't see her using any kind of intelligence when she fought Erza during Tartaros arc... >_>

One-shotting Tempesta? With what attack? Yagdo Rigora? Base Tempesta took plenty of fully charged attacks from PoF Natsu whose forte is CQC and power and actually overpowered him. I think it's safe to say he can still fight after taking an attack a non serious Kagura and a Pre-SO Erza tanked.

That'll be exactly like Erza's ability then. And yet even with that ability, Erza still struggled against many opponents.
