If your party fails at that mechanic more than 2 times and they r aware of tht mechanic then u really need to call em out and say dps is piss or dumb.
Cuz i had a group where the tank told them to hit the boss due to the mechanics and they just went on failing wipe after wipe.
The captain shot me for
All my hp which is a whooping
6.6k hp ( no food) + stoneskin ( so another 1.2k hp or so) + a benediction at 500ish hp + a swiftcast stoneskin.
So thats around a total of 14k hp of dmg done.... To a healer.
