I had a lighthouse run that was possibly the worst run I've had in a long while a couple of days ago
I was main tanking and knew something was off when half the raid died on just the first boss. Mentor mode kicked in and I explained the major mechanics of the next bosses and did call outs as best as I could while tanking.
Then came the math boss. I never had the fight take as long as it did. When tartarus mode. Raid A had only a tank and healer alive. I told everyone to focus on getting them up after we got out because they weren't going to make it. I kept doing callous as best as I could but I can understand the frustration and not being able to read chat and surviving as the same time
Everyone was more dead than alive the majority of that fight that we got 2 level 3 limit breaks. Boss eventually went into repeat mode with 3 attacks and the spin of death killing everyone that couldn't keep up. I think I was the only one who did not die lol(I was the only one left in my party that had the damage buff).
Last boss was a single wipe to add enrage but next pull but we got that down fast.
