Mythical Zoan Phoenix Devil Fruit, updated; limitations

Yep, I saw this on wiki, and the info is based on the latest SBS, turns out that the flames are not hot nor they spread like normal fire, they are actually healing. I dunno if they still behave like "hotter fire than Ace's" in the mean of blocking attacks (Marco could block Akainu's attack) ... but I guess it does not behave like it (he probably blocked it with his ability to heal allowing him to survive that)
Also the user IS able to take physical damage in phoenix/hybrid mode, he is not intangible like logia users.
