Would also like to see Mercy Stroke as like a 6 second DoT that triggers the on-death heal.

On outside world mobs, I have been able to time Mercy Stroke. In instances when I've tried, I will hit Rage of Halone (or some move), then execute Mercy's Stroke after. And for times where I've "killed" the mob in the log, the log shows Halone that finished the enemy. Where I would think if Mercy Stroke is executed after, it would register after RoH, not before. Not sure if it's the same on Warrior?

E.g. Pressing 1, then 2. But 2 happens before 1.
