The fight against Doflamingo ended and i still don't get how it works. Jozu's entire character revolves around his strength even more than Marco and some admirals. I think only Garp has better portrayal in strength category, but somehow from the brief moment he was caught by parasite, we got no idea if he could get out or not. Oda didn't show him move to even think if it was possible, yet suddenly during this arc, G4 Luffy snaped out of it with unknown reasons.
So it makes me wonder. Was physical strength really the issue? Or was it a change in form due to rubber properties to deflected the strings? Because i've a hard time thinking Jozu couldn't break that thing if it was a physical issue since it would also mean that at the very least weaker character(in physical strength) like Marco or admirals can't either despite the fact that they are portrayed to be stronger than Doflamingo.
I really think parasite was handled very poorly by Oda and he didn't even try to explain how to get out of it during the entire arc, chosing for Doflamingo to never use it despite it being his favorite attack preskip, only finding it convenient to use it by the end and give a mysterious reason for Luffy to break out
