well, there must be a difference between paramecia awakened and logia awakened...
I think there is, but it's impossible for us to say at this point what that may be.
Currently, all clues point to the fact that Monkey Dragon probably has a DF that manipulates the Wind or creates storms. So if Logia users can just awaken their DF and Manipulate the weather that would devalue the powers of Dragon. How is Dragon's fruit special if Akoji, Akainu, Crocodile, and possibly Kizaru can pull off the same feats while awakening their fruit.
That's why I disagree with the manipulating weather theory. IMO Logia awkening should be able to possibly alter their enviroment to benefit their DF, but full scale weather maniulation seems a tad extreme IMO.
