It's about time Shield oath and Grit become Abilities instead of Spells. (off-GCD)

I'm not intimately familiar with WAR so I can't say for sure. But from my understanding, Butchers Block is a DPS gain if used once every 2 minutes, or used when you will cap out on beast gauge by using storms path. Butchers Block combo is a 30 potency gain over Path, but generates 10 less beast gauge.

Ideally, there will be 0 Butcher's Blocks used in a fight. If you are going to overcap or need to utilize an infuriate you will use a spender. They do not break your combo, so there is no reason to alter your rotation. Outside of onslaught which will primarily be used for movement, there will be no extra enmity generated in an ideal DPS rotation - just like DRK, and will need to similarly frontload enmity and utilize shirking with the co-tank to manage threat through the encounter.
