It really needs Nerfed already or just made optional entirely. Tried for over 8 hours to clear this Ive tried every tweak to my DPS rotation , Best gear i can possibly have at Level 70 , watched 4 or 5 videos explaining every mechanic , and did both DF and PF there simply is no way to clear it for me. I even went to my FC of 140+ people and tried getting help from ones i guess who somehow had super luck in beating it already. The Boss has too much HP and stacks too much damage that healers in every run I did cant keep up even more so on the second phase when the platforms can be removed. If the platforms after say 45 Seconds would return it would be easier. The echo would help but im not sure how well since like any Dungeon run or Trial people are likely to quit after a wipe or 2.
