Cataclysm one shows one thing like what 2012 did.. survival after changes. That is the message to the trailer. The torment, the anger Deathwing have is really explainable, who would want to be healed from wounds with fresh hot from the anvil metal plate to seal some flesh wound?

Despite the wreckage Deathwing brought in, it does bring some fertility to certain land....

WOTLK one have a twist in it. To be a King, a different King.

IMO, every of the trailers out i love all of them. Best music score and cinematic direction combo goes to Classic trailer. The feel of "epicness" never fail each time i watch that.
