You know I'm trying to avoid using the word 'plot' in my explanation lmao, but honestly that's the explanation we got so it works for me, also Yajima admitted that Natsu and Gajeel were completely out of Sting and Rogue's leagues so there's that to go with, Minerva also knew that the Twins wouldn't win so that fight isn't exactly as bad as it looks..that's funny because he didn't saw Laxus' tempo, Gajeel's tempo, Zero's tempo, Future Rogue's tempo and etc. nope, that explanation sucks. Erza being stronger than Kagura and Minerva(via SO) is the same shit as that imo.
Anyway, the only 2 Sabertooth mages Natsu can beat are Sting and Rogue, Gray beat Rufus who's stronger than Sting and Rogue (but lel Natsu has always been stronger than Gray apparently)..
Btw, Future Rogue is one of my favorite villains because he completely shit stomped Natsu twice, even when Natsu had help F.Rogue still had the upper hand..
