So what you're telling me is that you're finding the fight difficult. You're using that assertion to make an argument from authority, claiming that nothing I say is valid.
I'm sorry you're wiping. I'm sorry that your tanks aren't able to multi-task with their CDs and their high-damage attacks. The math is in an earlier post if you're interested. The fight is doable, it's just not going to fall on day 1.
Spoken like someone who doesn't know they increased the damage output as well as the HP of this fight.
This fight is impossible given current enrage timer.
