Various Abilities and AoE Tanking in WoW

AoE Tanking:
For AoE tanking you'll use the same rotation as single-target tanking to an extent, but you'll use Thunder Clap and Shockwave whenever they come off cd before you use SS and Rev. You'll still tab-target to get to each mob for high threat on each, but TC, Shockwave and not to forget Damage Shield should be sure all the mobs stick to you over all but the highest dps. In between mobs, you could use Cleaves, but your rage is better used on single-target(buy wow gold) abilities in between your AoE abilities followed by target switching.

Various Abilities:

While your AoE tanking you might want to remember Retaliation in the Arms stance as well. Here you can get the most secure WoW powerleveling. It's not on a shared cd with Shield Wall anymore and will provide you with 20 quick attacks against all the mobs fighting you. A nice bit of aggro for a few seconds effort.

In both rotations you'll want to remember Recklessness as well for some fast aggro on a single mob, especially combined with Impale. You could pop it just before a pull to give yourself a nice lead before dps starts. On the same note remember that the Orc's racial Blood Fury no longer has a healing penalty and provides a decent tps boost for 15 secs.

Lastly, Berserker Rage is now usable in all stances and provides not just the immunity to fear, sap and incapacitate effects, but also extra rage from being hit for 10 seconds. Extra rage for no cost? Something to pop whenever you don't have enough rage for any of your abilities. Alternatively, and a tactic you have been using more and more frequently, you can pop Berserker Rage right before you Charge into a mob. A typical pull will be Bloodrage–Heroic Throw–back away from the mob–Berserker Rage–Charge. This pull-style will provide you a very large amount of instant rage for that instant threat, and keep the rage coming in for those 8-9 Berserker Rage seconds, with no drawbacks.
