Pulling max threat:
One mob: starfire, shift to bear, FFF, Mangle.
Two mobs: starfire the second kill target, while you're casting switch to the first. As your starfire is cast on the 2nd, moonfire the first and get into bear (helps if you have bearform hotkeyed here). Proceed to build threat like above.
Multiple mobs: Hurricane from max distance, the furthest side of the hurricane should be cast on the closest mob so they all run through it. Get into bear, demo roar, and start swiping. Mangle the first kill target.
Skill rotations:
One mob, limited rage: mangle, 3xlacerate, repeat.
One mob, unlimited rage: mangle, 3x lacerate, always queue maul.
Multiple mobs: try to sort of get some hits in on all and keep switching, for example :
mangle mob 1, maul mob 2, lacerate mob 3
maul mob 3, mangle mob 2, lacerate mob 1
and so on, and swipe every now and then (remember that turning your bear butt towards CCed targets will allow you to swipe to your heart's content !)
That's what I do, anyway.
