Ace was pretty strong back then, so we can't really tell. Burgess did, if I recall correctly, take attacks from both Garp and Sengoku and was still laughing. It's not just Shiryuu and Teach, there's also all those supposedly incredibly dangerous level 6 prisoners with him. You're underestimating Admirals too much. They are the justice equivalent of the Yonkou.
Deal. If DD shows himself to be close to an Admiral, I will state that I was wrong then and there.
Burgess tanked attack from Garp only in anime.
Also one more thing- it was shown that BB crew during Marineford War wasnt killed by Sengoku + Garp combined.
Two fighters slightly under level of Admiral combined were not able to beat/overwhelm Blackbeard and his crew.
So why one Admiral should be capable of beating Doflamingo, his seats and rest of crew.
Impossibility - as for Law and comparing him to Doflamingo Seats, they seem to me to be only slightly under Doflamingo himself. Same as Zoro and Sanji are slightly one and two steps under Luffy. Law was shown as only a bit under Doflamingo overally so I put him and Seats at same measure so to say. Remember that Laws ability tires him more he uses it and he tried to conserve as much as possible when he was going to Green Bit he even avoided fighting flying fish to preserve what he can as he planned to go against Doflamingo. Then he fallen for Doflamingos trap and had to fight Admiral and Joker only by himself. That depleated him a lot so when he was fighting on bridge he was tired already. Last scene where we seen him he was out of breath mostly. More tired you are, more your rection time gets longer and overal fighting capabilities drop.
I said that Doflamingos crew is behind Yonkos crew. Thats all.
Also Doflamingo expected likes of Lao G to be able to hold his ground against Burgess, Bartolomeo or Luffy. He is also quite sure that Diamante is more than enough to handle those fighters. Even if he is wrong that speaks volumes about how strong seats must be.
What makes you think that Blamenco, Rakuyu, Namur, Blenheim, Curiel, Kingdew, Haruta, Atmos, Jiru, Fossa, and Izo are so special? Do you take every one of them as strong as Law? Because I dont.
Ace, Jozu, Vista and Marco are threats. Rest is not comparable to Doflamingo Seats. Doflamingo made fodder out of Atomos. He was also capable of stopping Jozu without much effort, standing on him and smiling. Jozu was capable of fighting Aokiji for some time so difference between Doflamingos crew is same as difference between his strength and for example Kaido. There is clear difference but they are not fodders. Law said himself that it would be a fierce battle between Kaido and Doflamingo if Doffy would anger Kaido. Joker would get wiped out but it would be a fierce battle, not straight up ownage. Im just against idea of one Admiral being enough of dealing with Jokers crew and making them not as dangerous as they are.
KingOfNight- one new tought came to me. It was said that stronger somebody gets stronger that persons DF ability is. So if Doflamingo was able to stop Jozu with his devil fruit and we didnt seen Jozu being able to move even slightest bit, he just gotten pissed with vein on his head at Doflamingo that means than as person Doflamingo probably is overally stronger than Jozu. Jozu who lost to Admiral but he put up a fight.
