Like I said, Irene said that it takes more to pierce a dragon's scales than to split her deus sema meteor. Even if it were the case that the soldiers were damaging a dragon through pure strength, they would have to be hitting harder than Erza did when she broke Irene's meteor. Jacob doesn't have this level of strength anyways. Jacob's knives doesn't even penetrate Natsu's bare skin, and his hand to hand attacks don't do enough damage to serious injure Lucy or an exhausted Mirajane without takeovers. I honestly don't think Jacob has the means of taking out Wendy with his strikes...let alone a dragon.
The GMG dragons were fighting the entire Fiore forces. Kagura and Erza had swords much better than a regular spear, and they couldn't scratch any of the dragons. When they were planning to fight Acnologia, Erza even shot down the idea that swords or physical objects would be effective.
Well considering that Ajeel is weaker than Jacob and he manhandled Erza without help, then Jacob can be as strong as Erza and what she did was indeed BS.
what do you think that means, do you even think what you said sounds correct?
Ajeel isn't weaker than Jacob. He has the exact same hype as any of the other Spriggans, and better feats than Jacob when it comes to AOE and attack power. At least Ajeel can seriously injure Erza and Elfman. Attacks like Sands of Death are better than anything in Jacob's arsenal. Even that attack was countered by one of Laxus' casual lightning bolt, and Erza's at her strongest scales all the way up to red lightning. Also, Ajeel doesn't hit harder than Erza. Ajeel was beating Erza because he can create a city-sized sandstorm, and his sand was absorbing all the moisture in Erza's body (Jacob can't replicate any of this). In terms of his actual striking power, Ajeel has nothing even remotely close to Erza's meteor slashing strike.
It means I have limit for the amount of crazy claims I can take in a day. Hearing you say Jacob's hand to hand attacks and knives can do more damage than Erza's meteor splitting slash puts me at that limit pretty fast.
