I've seen mention here that Devastate is low on priority which is an idea I would contest. Shield Slam is your highest threat gen ability and devastate has a chance to proc Sword and Board which takes your SS off CD and makes it cost zero rage for the next 5 seconds. If you are not keeping Devastate in your standard rotation then you are missing out on a lot of potential threat gen. For initial treat I would also pop Shield block before your initial SS to give you a nice bit of extra threat which can help at the start.
When you have a lot of surplus rage, start queuing Heroic Strike for extra threat just don't let your rage get depleted while doing this as it may leave you short when your SS come off CD.
