I keep forgetting that there is actually a second part of how Devil Fruits should reasonably work that I feel like One Piece does not take into account at all.
This is: the relevance of experience in having your Fruit.
Devil Fruits Users are weird as hell and it's even weirder to suddenly experience being one. They put you fundamentally in a different category of being. Big Mom's Fruit is basically running Tottoland, because she's had it for 50+ years. Whitebeard is able to use the high-damage, wide ranging area-of-effect Gura Gura no Mi with incredible precision, because he's presumably had it longer than most people have been alive. Yet we have characters like Blackbeard and Kalifa up and swinging hours or even minutes after eating a Fruit. Kalifa even develops complex methods of using the Bubble Bubble Fruit defensively when one of the main drawbacks of Paramecia are how varied and difficult they are to plan for.
I don't understand how One Piece emphasizes the value of training and having experience in fights while simultaneously this is happening with Devil Fruits.
