Wow gold is all-purpose

The first thing you need is an uncrittable pet. With lower health pools than standard player tanks, your pet could easily be killed by a single crit. Your pet talent Grace of the Mantis will reduce its chance to be crit by 4%. Since a raid boss has a 5.6% chance to crit, that means you need to lower it by another 1.6%. You can do this by getting 132 resilience rating. Your pet gets whatever resilience you have, and the 132 resilience will lower your pets chance to be crit by 1.6% (yes, it will; yes, it works to reduce threat, even in PvE). Of course more resilience is fine, but any extra resilience isn't going to help you at all about making wow gold. Note that the damage reduction benefit of resilience only works on attacks from players, not bosses or mobs. All we get is the crit reduction.

Now that your pet is crit-immune, your next task is to be at the hit cap. This is vitally important for your threat generation. Keep in mind that if you're at the hit cap, then your pet will be hit-capped and expertise-capped. This means that your pet cannot be dodged or parried, in addition to never missing the guide of making wow gold. That can add up to more than a 20% DPS increase for your pet when tanking! You will need to get 263 hit rating. You cannot use Focused Aim to reach the hit cap -- while the hit all transfers to your pet, for some reason the expertise doesn't translate as fully as it should.

So get all of your hit through hit rating on gear. Go buy Mark of Supremacy if you're struggling with hit. Finally, it should go without saying that a skilled pet tanker is far better than a foolishly ignorant and stubborn idiot tank. If that silly DK tank isn't even crit-immune, you're probably better off having your pet take care of the heroic. As a game player, we should know the importance of wow gold. With the wow gold, you can buy all in the game.
