3. NOTE: never tried this part, so it's theoretical - After the adds are dead, drag the JM over near the boss and continue AoE. This can get a little tricky depending on the boss's location due to JM's knockback, but it should hypothetically allow for more DPS on the boss since you're not taking the time to focus fire the male. As long as the male is dead before the next pool there's no reason to take DPS from the boss to burn the male.
You probably don't want to do this.
The Jealous Male goes into a frenzy whenever he it within a certain distance of the boss. In effect, his damage increases. You should keep the Jealous away from the boss at all times. Though taking him near the red pools is a good idea (as long as the red pool isn't near the boss's current or "next" position).
