Well, yes, the fires are different, but that could be said about almost any other logia, which is the entire point. They are different in name, temperature, and some in powers, but ultimately they are still fire, which is where I see the issue. I suppose a better example would be my classic rock/ground example. We have a rock Logia and a granite Logia, the only difference being one is rock in general, the other is specifically granite, which is a type of rock. Logically, they are the same, but it can be argued that since one is specific they are different. Now we also have clay and ground as logias, which could be argued that they are ultimately the same (e.i. ground logia) which one could also consider the rocks and mineral logias part of that as well, as they make up the ground. Even Crocodile's Suna Suna no Mi could be thrown into the pot as well. We should try to find a rule for it, however difficult it may be, seeing as most of us have different opinions on the subject, and there are many loopholes and factors that need to be considered. Either way we can all agree that every user should check the DF shop before creating a fruit.
