We managed to kill Kephess 8man HM we wiped the first time because people were slacking and missed the interrupts on the last droid (we died to the purple sludge on ground)..
2nd attempt, cleared it with little effort now that people were actually awake and paying attention, unlike the we just used to go in not focus and face roll. Other than those interrupts... Same fight same simple mechanics.
And we had the healers doing interrupts as well. Downed middle, left, then right as you look at walker from entrance. And this was with our Rakata alts and maybe 1 or 2 people in Campaign/BH quality... Just focus the interrupts assign a rotation and call it a day!
Say we had two Merc healers and one Merc DPS in one of our raid groups. How do you suggest they manage the interrupts considering their interrupt channels and they only have 1 second to interrupt the droid?
