I have to admit, I'm kinda disappointed that Oda had to basically handicap Doflamingo for Luffy to stand a chance.
Better than Sabo coming to the rescue, but still.
Also, Law and Doffy's Devil Fruits are overpowered as fukk.
I mean Law's was overpowered from the start, but now dude can have rooms the size of football fields and smaller rooms inside of that? Plus he can maintain that even after having his arm cut off? And Doflamingo can stitch up his organs whenever he gets hurt? While maintaining a country-sized birdcage? Plus he had a string clone running around earlier?
Meanwhile all Luffy can do is stretch.
Dont forget that law has been shot more times than Sean Bell this arc as well.
