People sabatoging the last boss of deep dungeon

[Zumi]

I have yet to beat the last boss of deep dungeon floor 50 because there is always someone trying to wipe the group. The problem with the boss is that there is an instant wipe mechanic if you get hit by 5 aoes these people are purposefully trying to get hit. I seen people dance the whole time standing in AOE while not attacking the boss that is how I know they were trying to make the whole group die on purpose.

I have wasted about 6 hours of my time so far with this. It takes 10 clears to get the mount I can't get a single clear cause someone is always trying to sabotage the run. I am trying very hard to get my mount and pets from this content.

SE needs to take out the instant wipe mechanic of this last boss it just promotes this type of play. There are no retrys on this boss they wipe you and waste 1 hour of your time. Something needs to be done SE and soon.
