Should probably
three heal this boss when you first progress on it because of the high damage and it does require healing on adds. Overall damage is just really low on the boss, too. DPS should try and pick it up.
To control the adds, put a raid mark in one spot. Only have ONE DPS hit the adds NO MATTER WHAT. If you get high stacks, have the other dps stand there and let them fall off. This stops the adds from running wild. Have the dps and tank that picks up the adds all at the raid mark, will make the adds less of a clusterfuck. We did this strat during our progression on the boss.
On your longest pull, overall damage on Immerseus was very, very low.
