The Care and Feeding of Warriors is all about your favorite meatshields. Matthew Rossi used to tank for people who called him that all the time, and honestly, he didn't like it all that much. He preferred 'Dislike Management Engineer', but folks are still gonna call you meatshield so you might as well get used to it.
After a burst of frenzied PvP activity to get the Gladiator's set, I've found myself in a cooling off period towards it. My wife and I are exploring the arenas on the Alliance side, but as for the Horde, I have to admit I haven't been PvPing much at all lately. So the other day I went ahead and respecced prot to get back to my roots as a tanking warrior. As arrogant as I am, I was still a little worried that I'd be rusty, but a quick trip into Heroic Sethekk convinced me that yes, Virginia, I still know how to tank. As i gear up to start tanking in ZA and maybe SSC (crossing my fingers) I wanted to talk about the other half of the equation of tanking. The first half is making sure you generate threat. After all, you're there to keep the mobs focused on you instead of the rest of the party.
The other half is in being hard to kill. You need to be as hard to kill as possible, because your healer has limits, and anything you can do to reduce incoming damage to a steady, manageable level is something you should do. In addition, anything you can do to make it so the healer has more health to work with is also something you should do. You must maintain threat, of course, or even the best healer can't prevent a wipe. But even if you're a genius at generating hate, if you only live for a few seconds once you have focus fire on you, then your healer is again unable to prevent a wipe.
