You'll also want to learn Ghoul control. Don't keep your abilities to make wow gold on autocast. You'll want to be able to cast Leap, Gnaw or Huddle at a moment's notice. You'll especially want to get good at using Huddle and Leap to help your Ghoul outlast or escape if it gets focused for killing. Remember, your Ghoul can use Leap to leap to an ally as well, which can be great for support or escape purposes.

As far as which presence to use, all three have their place. Frost Presence is useful when you're getting focus-fired, and many arena death knights like to keep it on at the beginning of a battle until they're sure they aren't going to be focused to start off. Blood Presence is still a good heavy hitter, but many death knights will stay in Unholy Presence in order to squeeze out more quick burst damage thanks to the shorter global cooldown and for the run speed increase. As you fight more and more, you should start getting a better feel for what works and what doesn't, so keep it at it. The more you fight, the more wow gold you will get.

Especially check out Art of War(craft)'s series on countering each class, even death knights themselves. I'd especially recommend checking out our Blood Sport and Art of War(craft) columns for all the latest PvP tips and tricks. If you know what tricks the enemy's expecting from you, it's easier to figure out your own ways to counter. Learning more ways to get wow gold is the important thing in the game. With the wow gold, you can buy weapons and items for yourself.
