Charge is great, and TC will get the mob's attention. But do not use SW right away, because if the whole mob gets stunned, there goes your aggro. Also, Cleave will consume massive amounts of aggro. You will probably have to get used to tabbing, and devastate and Shield Slam are your primary attacks. After you charge and build up a little aggro, back up a touch and line the mob up for a Shockwave. Then slap devastate on the whole mob with some shield slams or revenge (it now hits 2 targets) mixed in, depending on cooldown.
Shockwave and TC are great for multiple targets, but don't use shockwave to early.
Always stay behind your tank and in front of your healer.
