You seem to not be understanding what I'm saying here, I IMO don't think them as rookie, I specifically stated the one piece world views them as such, my opinion on the matter doesn't count now does it?
For example whitebeard called everyone at marine Ford brats akainu,kizaru, aokiji everyone except garp and Sengoku. Does that make them brats?
From my perspective the worst generation aren’t rookies anymore. They have way to much experience to be considere that. Compared to this pirates who have been roaming the seas for 10-50 years. Yes the might seem like rookies in their eyes.
