Ive said it before in another thread, the size of Dany's army is a weakness in it's self. The dragons need to eat, the men need to eat, the horses need to eat.

Winter is here so nothing is really growing anymore, so it's all stored. While it would be bad for Dany, and well the civilians too scorched earth would be interesting to see. Done by Cersei of course, the only one crazy enough to do that shit.

It's happened in history many times...

As the Russian army fell back, Cossacks were given the task of burning villages, towns and crops. This was intended to deny the invaders the option of living off the land. These scorched-earth tactics greatly surprised and disturbed the French, as the willingness of the Russians to destroy their own territory and harm their own people was difficult for the French to comprehend.

Jorah said that Dany has a kind heart, I still think this is true, she is a kind leader invading a nation run by a psychopath....

But Yeah, Dragonbinder would be badass.
