This is not just an injured Doflamingo, he was injured enough by the gamma knife back then and this was brought up by luffy many times and after the onslaught of gear 4 doflamingo is clearly at death's door, he even pointed out that he doesnt have enough stamina to fight the fodder warriors from the colosseum, after waking up from the lion bazooka or something Doflamingo was trembling around and was wobbling while fighting the colosseum fighters, the guy is barely standing while the warrios+ zoro+ a complete healthy cav would be enough to bring down doflamingo, Luffy isnt the only ray of hope, how can an out off commission guy be the ray of hope at this rate is ridiculous because there are many strong enough fighters to gang doflamingo, hell an healthy Zoro would be enough, we usually tend to like OP because of how well written it i compared to other shonen mangas, but no matter how well written we think OP is its still sticking to the shonen cliche that the main guy is the main hope to defeat the main villain, I loved One piece because its unpredictable and that's what's so great about this manga but everything is so predictable now that its laughable at this point, I can certainly see how Luffy wakes up and beats the hell out of Doffy in the last second before birdcage closes into the people, its forced drama, no matter how u look at it.
What I loved about part 1 OP is that Luffy got to beat the main villain of the arc not because of the shonen cliche but because he was always the only guy on the island/country strong enough to defeat it but its not the same case here, everyone screaming that Luffy is our ray of hope when u literally got the nr.2 revo in the island and one ****ing admiral who for some weird/unknown reason is ready to see thousand of people die and on top of it u add someone with the power of healing fighters temporary and reviving the colosseum fighters adding more question-marks as to why they dont just gang on Doffy and for some stupid reason Kyros who healthy would be enough to beat doflamingo at this rate prefers to stay injured even though before he said that I didnt come for a 1v1 after beating diamante, and the most weird of all she doesnt heal Luffy but heals an running fodder around dressrosa who's ankle is tripped, the number of inconsistencies in this chapter are unreal and stupid.
