At least the good thing about Acnologia speaking is we'll get to see how awesome his voice sounds when the anime gets to this point (hopefully the animators don't find a way to screw that up)

About the dragons, they will probably be affected by Face, since I guess it doesn't matter what kind of magic it is. (Here's a random thought: What if since Face was made such a long time ago, it doesn't work on newer magic and only affects the dragons, ancient/lost magic, etc.?)
