Logia Awakening isn't what People think imo
I believe Awakening doesn't grant you New Abilities, it simply Pushes your Ability beyond it's "Limit"
Zoans for example, They don't gain New Abilities or New Creature to turn into, They simply gain a Physical Buff (Whatever their Zoan Creature can do, They can do it even better after Awakening)
Paramecia Awakening doesn't grant you any New Abilities, it simply allows you to do the same but without being Restricted to your Body only as center of that Power, you can make your Power apply on more Targets such as Law making his Sword/Big Mom center of Room instead of him or Kid turning a Wall into a Magnet ... etc)
So Logia Awakening DOESN'T GRANT ANY NEW ABILITIES, it simply makes Logia Advantage even "Better"
In other words, their Intangibility is "Improved"

Logia Awakening = Intangibility even against Haki !! (At least CoA)
This is why Akainu replied to Marcy & Vista by saying "Haki Users"!
If He was using Future Sight to dodge them, He wouldn't criticize their Haki, They were simply not Fast enough
But the Fact he grouped "Haki Users" together indicates his Intangibility is Greater than a Non-Awakened Logia
Zoan Awakening = Super Physique
Paramecia Awakening = Super Expansion
Logia Awakening = Super Intangibility
Admirals, Crocodile & maybe Enel are Awakened
