Wow you're a retard. Of course he can speak in dragon form. Haven't you read the books? Haven't you seen the cinematic? There are also many scenes in which he is in dragon form and speaking. Fucking learn more about the story of Deathwing before posting about him, dumbass.
STFU with your "not another dragon" shit. This is Deathwing the Destroyer, one of the major lore characters, you idiot! He is in most of the Warcraft books. If you don't know who Deathwing is then you haven't read the Warcraft books and you don't know shit about the Warcraft story. You're just a pathetic noob!
