Lootship.
The first two bosses had some simple mechanics, then there was lootship, and then there was a serious DPS and threat generation check. It wasn't until you got into the upper wings that things got really interesting.

Moving Lightning Bolt was a Cata innovation, to my recollection. WotLK brought Lava Burst.
