Tanking Quiz!

[Concillian]

Think you know tanking? Answer these questions! I stole them from a guild app thread, thought some people might get a kick out of answering them.

Note: if you are unfamiliar with an encounter (such as Teron Gorefiend from question 4), feel free to look it up in WoWWiki or somesuch to research the boss' abilities and then give an answer.

1) There are 3 stats that improve a warrior tank's threat generation. Which are those stats. (bonus if in order from better to worse).
2) What Cloak enchant is better for a warrior tank? 12 defense, 12 agi or 12 dodge? (bonus if in order)
3) What is the worst tanking stat an item could have while aiming for uncrushability, and why?
4) You are tanking Teron Gorefiend, you pop bloodrage and run in. What is the first ability you need to use when you run in?
5) On an untauntable mob, you have the job of building second aggro. What ability you do not want to be using under normal circumstances when building second aggro as a warrior, and why?
6) Normally on many heroic bosses, when running with one of our mages, the Warrior tank would ask him to pull the boss with a Pyroblast with all he's got. Why would I do this? (tip: no, its not to get him killed lol)
7) In Sunwell Plateau, the first boss fight has a demon that performs an ability called Corrupting Strike. This ability deals a vast amount of damage and also knocks the tank down. What makes this ability so dangerous, and why?
8) Illidan Stormrage performs an ability called Shear, which greatly reduces your health, turning any hit in a posible one shot on the tank. As a warrior you avoid this ability by timing your shield block. But since you need to time your shield block, you cant use it freely, so: How do you avoid Illidan crushing you?
9) Warriors are normally the best tanks against elemental type of mobs (like Ragnaros or Hydross). Why is this?

I'm not going to answer, but there are two significant ambiguities

1) There's way more than 3. There may only be 3 on most tank gear, but there's way more than 3.
2) For what purpose? Threat is a different answer from avoidance / uncrushability. Also there is max effective health to consider, which is also different from avoidance / uncrushability. There is not enough information to appropriately answer the question.
