Yeah that comp got quite heavy CC with Throwdown > Scatter Trap > Fear every 45seconds.
Also double fear to get Tremor totem on cooldown against enemy shamans.
So First Throwdown > Scatter Trap > Warrior or Priest Fear (uses Tremor)
next 30seconds Scatter Trap again > Warrior or priest Fear again > then Throwdown is off cooldown again.
Just have to connect damage/burst really well sicne it's lower damage then a DK.
Well we usually use our cc(besides priest fear) to interrupt heals that are midcast, and in most cases we use throwdown on a dps either for a kill or a peel, or just to get offensive pressure going. But yea, the cc is definitely way better in war/hunt/priest, and like you said its nice to get tremor out of the way easily with warrior fear so we can get a full priest fear when dr is up.
