@Jabra:
I think Aokiji's attacks are nicely shown against Saul. The flash-freeze type from a distance merely "coats" the opponent in a layer of ice, while the direct touch turns them into popsicles. Since his hands never left his pockets it was obviously the first type.
So not surprising that Doflamingo could escape (albeit with some effort).
How did he do the flash-freeze anyway with his hands in pockets? What if he put his hands in the pockets after the attack, signifying that he doesn´t want to fight unless forced to (of course also being badass)?
I imagine his attack like a slap/splash, with the freezing sound. But one picture showed the whole area being frozen, while Smoker, both Baby5 and Buffalo and also the G5 bystanders (not the the ones Dofla KOed) were untouched by the wave. Complete DF control?
Also to the person who said Whitebeard survived thanks to Haki back then, reread it. Kuzan himself said something like "guess I can´t freeze vibrations"

EDIT: List of people Kuzan froze in the story (from the top of my mind):
Saul - solid, for good
Robin - solid, bcouldn´t break himself free, defrosted later by others
Luffy - solid, couldn´t break himself free, defrosted later by others
Whitebeard - solid for 1 second, broke free thanks to tremor DF
Jozu - solid, couldn´t break himself free, defrosted later by others
Dofla - solid for 1 second, broke free…let´s agree that he´s stronger than the ones that didn´t break free.
