It could mean, Logia Awakenings are
THAT STRONG, but if Oda's gonna reveal it with Akainu - Kizaru - GB in SHs vs Marine HQ, we may have to wait 5 years
But, here may be my best argument for Logia having Awakenings :
■ PH : Logia themed arc ( in Villains & Marines side )
Villains : the only 2 Logia users of Donquixote Pirates
Marines : Smoke Logia
Awakened Logias : could only be Akainu & Kuzan
■ Dressrosa : Paramecia
Villains : all Donquixote Pirates other than Vergo/Caesar/Monet, whose DF users were all Paramecias
Marines : Gravity and Wash Wash Paramecia ( Tsuru ), although Sengoku didn't fit
Awakened Paramecia : Doflamingo
■ Wano : Zoans
Villains : 99 % were Zoan users ( including 500 SMILE users )
Marines : Allosaurus Zoan, although GB didn't fit
Awakened Zoan : Luffy
■ BMP was also Paramecia themed, full of Paramecias.
So WCI was a Paramecia themed arc in Villains side, with 1 Awakened Paramecia shown
