What WoW Class are you?

Read the title, got nothing else to say than that Question. :P

1 Your enemy attacks you critically, what do you do?
2 Your ally is in serious pain and WILL die if you do nothing.
3 What do you prefer...?
4 What would you rather call your character of these options?
5 Was the question before this one too obvious?
6 What class do you rather play? (I'm so tired, imba questions)
