Are there any plans to introduce new outdoor raid encounters, such as Lord Kazzak and Azuregos?

Are there plans to allow for pet scaling in the end-game raids and dungeons?

It's possible, but there are no plans to do so at this time.

Will it be possible to kill Illidan in the Burning Crusade?
Illidan doesn't think so. As a matter of fact, he's probably thinking about destroying your character for simply entertaining the thought.
