I consider Micah's skill to be one of the few useful "DPS" skills.

Not so much for the DPS, but for the aggro pull. Any enemy damaged by it will activate and come running to my characters, which is far safer in terms of keeping my ranged characters from running up in front of my tank.

Only problem is how inconsistent it is. If you don't hit any of them, you don't pull any of them. If you hit too many of them, you may overwhelm your tank.
