Just did it too. We spend an hour on it last week and every pull was fine. We did it tonight and he just kept tearing our tank within the first 5 seconds of the fight.
Herald run is basically undoable atm. Please, fix ASAP.
Are tanks actually taking more damage? or are healers just not able to keep up as well since prepatch? If tanks are actually taking more damage, then one hypothesis I have is maybe bosses are being calculated as level 88 instead of 83. If it’s same damage, then I wouldn’t be surprised if healers couldn’t keep up as well.
I m leaning to the “more damage”. Looks to me like tanks in general either take no or very little damage for the most part (avoidance) but if they get hit migitation isnt really doing all that much without cooldowns
