Well.
Anyone using KC when Burning Adrenaline?
Or U wait for ChimS? (when its about to come back from CD).
Or U use ArcS immediately? Or AimS?

Lets say the situation is:
1) Pet always on boss
2) No-running-around phase
3) U've got 100% focus
4) Boss is 50%
5) No haste buff

[Metaphoric]

Under those cirumstances, I'd use Chimera Shot if it is about to come off cooldown, and Kill Command if it is not.
