@Real Godisme -> Minerva was the strongest in the guild overall. But when it came to strictly offense, Orga was the strongest.

Kagura was too busy with Erza and the fact that Erza was the one who saved her when she was a kid. She was confused. Minerva stroke at the moment Kagura was the weakest. In a one on one battle, just Kagura and Minerva, no hostages and any other BS like that, I heavily doubt the latter would have been able to pull off the same trick.

http://img4.mangasee.co/series/FairyTail/0312-010.png -> A kick from a non serious Kagura. http://img4.mangasee.co/series/FairyTail/0312-013.png -> An attack from that same Kagura. Great intelligence and reflexes from Minerva here btw

http://img4.mangasee.co/series/FairyTail/0321-013.png http://img4.mangasee.co/series/FairyTail/0321-014.png Pre-SO Erza managed to react to Minerva's CQC while being heavily damaged and with a broken leg. Fresh PoF Natsu and a Serious Gajeel are way deadlier than a half dead Pre-SO Erza.

Natsu is very fast and agile as you can see here. http://img4.mangasee.co/series/FairyTail/0402-003.png http://img4.mangasee.co/series/FairyTail/0402-005.png http://img4.mangasee.co/series/FairyTail/0402-006.png http://img4.mangasee.co/series/FairyTail/0402-007.png http://img4.mangasee.co/series/FairyTail/0402-008.png http://img4.mangasee.co/series/FairyTail/0402-009.png http://img4.mangasee.co/series/FairyTail/0402-010.png http://img4.mangasee.co/series/FairyTail/0391-008.png http://img4.mangasee.co/series/FairyTail/0390-010.png http://img4.mangasee.co/series/FairyTail/0395-014.png http://img4.mangasee.co/series/FairyTail/0395-016.png

And so is Gajeel. http://img4.mangasee.co/series/FairyTail/0390-011.png http://img4.mangasee.co/series/FairyTail/0395-014.png http://img4.mangasee.co/series/FairyTail/0395-015.png http://img4.mangasee.co/series/FairyTail/0395-016.png

These are only some of their feats. Minerva doesn't have the necessary reflexes to dodge much of their attacks.

Intelligence doesn't really mean much most of the time in this manga. Take Levy for example. She's even smarter than Minerva yet she would still get rekt by either Natsu or Gajeel pretty easily.
