The tooltip says Unique-Equipped: Alchemist Stone (1), so you can only equip one -- no matter what flavor -- at any time. You can have the intellect alchemist stone equipped in your healing set, and you can swap it out for the stamina stone when you switch to your tanking set, but you can never have both of them equipped.
Wasn't Deathwing the Aspect of Earth?
Indeed. He still is! Once he fell in with the Old Gods, though, they gave him a new role. He's not so much the guardian of Azeroth anymore; he's a herald of destruction. It would be odd for him to use the title Aspect of Earth when he's destroying it all.
Dr. Knox asked:
When a Chaos Orb drops in a heroic, I can't roll on it. Has the orb looting system changed since Wrath? Was my DPS not high enough, or what?
You need to have a profession that uses the Chaos Orbs leveled to at least 425 skill to be able to see them. If you don't have an appropriate profession or it's far too low, the game figures you have no use of the Chaos Orb and locks you out of them.
What makes Thoridal the Star's Fury exactly legendary? Who did it belong to?
We don't know who it belonged to at all. It's legendary because it shoots magic frickin' arrows. It's elven in design, so we can assume it belonged to some incredibly important high elf, but it's never been named who that was. In the case of Thori'dal, it was the strength of the weapon that was more important to adventurers than who held it in their hands previously. Presumably, nobody could be arsed into asking about where they bow came from after they stole it from one of the most powerful demons in existence. Because honestly, magic arrows. Do you need to know more?
