Unrelenting Wrath
Made myself a WA to help with the rotation:
1) monitors Beast shot. Icon appears when it's almost over (you can press 1 more skill, then bleed). Icon glows when there's no bleed on target. (ideally should not glow longer than 1 second)
2) monitors serpent sting, tells you when to press chimera.
3) monitors frenzy shot and pet's buff, appears and glows when there is no buff on pet and is off cd.
4) monitors the availability of kill shot
5) made a small pet panel to keep track of the pet's hp, focus, and buffs. I don't know who has which interface, it's more convenient for me that way. The first 3 buffs should be active in combat all the time if you're doing everything right. Focus should not be near zero.
