Maybe it's just me, but seemed like brimboil was losing ~8% hp every time it split off some babies, just cleared with JP group and we basically just killed babies over and over until the main nm was lowish hp and finished it off then the rest of the babies to clear the wave. Had a PLD party with 2 PLDs, one to super tank while other peeled off adds to feed to nuke-ga. Worked well until main boil died, then the adds just scattered but arent that high in HP so easy to kill off if you have enough elemental damage/accuracy. Pretty annoying if you have bad luck with the tower things, i think we didnt get NM pops until the very last ones both times, barely finished in time.
