After Kuzan used ice capsule on Saul, he doesn't throw projectile ice, but slowly walks towards him
Places his hand on his body and uses Ice Time
This is what happened with Jozu and the BBP commanders
Note how Kuzan uses his hands to off them
Think about it, projectile ice freezes your exterior, if you're left stranding for a while then you'll eventually be frozen to the core
However, when freezing on contact, Kuzan is instantly turning your body to an ice popsicle
You drifted too far from the discussion, Doflamingo could be YC1+ for all I care but this whole imaginary W of how Doflamingo escaped getting freezed needs to be discussed. He's not fodder as to get murked by casual flash freeze, but you can't compare this with Jozu and the goofy BBPs commanders. Even though it's a casual meme scene, we have to look at things objectively, these guys were directly frozen by Kuzan
It's still too early to judge but we will be looking at some next level powercreep. Van Auger for example will fight/ defeat Yassop, someone like him should fare pretty well against YC1 Doffy
