You're making a mountain out of a molehill, in an attempt to demonize me.
You said "Wrathion prefers himself in human form" and used his appearance before the Carapace of N'Zoth fight as evidence of your claims, saying that he transformed into a human form because he prefers to be in human form, and I pointed out the possibility that he has done so not because he "prefers to be in human form" but to keep his much larger dragon form from being entangled in all those tentacles that were coming to fight him, and because handling such a small weapon as a human-sized creature is better than a massive creature whose pinky finger is bigger than the aforementioned weapon.
To which you then went the absurd route of "then why didn't he just turn into a wolf, cat or bird?" And then I asked if we ever saw a dragon turn into anything other than a humanoid.
So I'll repeat the question: have we seen or have any records of dragons turning into any animal form?
