There are two demonology warlocks in our raid team (including myself) with same problem:
Last phase of Iron Maidens when Admiral starts placing turrets down, our pets start dying from the blast, almost instantly. The most intense part of the encounter, and we have to place pets on passive (sending them on one of the bosses instead on turret doesn't work either).
I tried managing pet, but it is impossible to walk pet around blasts and maintain dps at the same time.
Does anyone have any solution?
