If you've got a hunter of level 60 or above, presumably you know about Misdirection. It's that great spell that routes the threat your hunter's next three attacks generate onto the target of the spell. Tanks like it because it helps them build the aggro that much faster; you like it because it lets you open with some nice damage-dealing instead of worrying about ramping up your damage (and therefore threat) gradually.
But don't forget its value when soloing! There are times when it's very easy to pull aggro from your pet—say, when you're leveling up a new pet. Misdirection is a very valuable addition to your arsenal of aggro-shiting techniques, along with Intimidation, Aspect of the Beast, and so on.
