Hmmm, what about this macro as a battle opener ->

/castsequence reset=combat/15 bloodrage,battle shout,heroic throw,heroic strike

These are all instants. Heroic throw generates high threat and does damage based on AP. Herioc strike will be ready for the next attack. Then I will start a rotation sequence that would include more AoE type threat generators like thunderclap and shockwave. I will have to manage GCD's and manage a well placed HS in a click sequence. It isn't optimal and won't be because of rage generation but i will get something down.
