So my guild and I tried zerging 10-man Sartharion+3 last night (1 tank, 1 healer, 8 DPS), but we had some odd behavior. Whenever Tenebron would land, he would practically 1-shot anyone with a single breath. We're talking around 65k-75k damage from the breath. Not Sartharion himself, Tenebron. We didn't really test this with any of the other drakes, since we had a tendency to die before the second drake would land.
Did Blizzard do something to stop the zerg strategy from happening, or are such large drake breaths expected? I remember our earlier attempts the more established way (kill drakes, then kill sarth) and the drake breaths never went for more than 15-20k.
This is not new. It's always been the case that when Sartharion reaches a certain percent health (25% I think?), any drakes still alive berserk. If one of them uses its shadow breath while Berserked, it's most likely going to kill its tank unless you have a cooldown up and get him some big heals fast. As I understand it, that was Blizzard's attempt at preventing a zerg strategy where you just killed Sarth and ignored drakes.
