Went into Alliance Raid roulette as GNB yesterday and got Dun Scaith. Everything was going swell for the most part aside from my healers being slow to do their jobs at times. I died once or twice from the start till Diabolos but still managed to do my job as MT. At that point I had an IRL distraction going on and my focus was about half and half. Because of this I derped hard and stacked with the rest of the group for one of the first stacking mechanics. I cleaved the whole raid and killed everyone. Apparently it was some peoples' first time being killed this way too.

I felt horrible.
Then I proceeded to do everything right...until I died again because of slow healing. But up until that point it was going much better than the previous attempt and we managed to clear anyway.
