People who are trying to figure out what's going on here is that he is rotating between using the bubble and the PvP insignia trinket to break the sleep. He's not using them immediately so that he can mitigate the debuff stacks optimally. That being said he is getting lucky with the mine placement whilst he is asleep. He's also using the talent Holy shield so that he is doing thorn damage on block which will help do DPS whilst he's asleep, and using the Unbreakable Spirt talent to reduce bubble cooldown. Honestly this boss is a pain in the ass, and is very luck based. Main thing first is the dps check needed to get through the first phase. Though it is possible - My recommendation is to create a small group using the legacy raid finder rather than attempt this rage -inducing ordeal. Good luck if you do try!
hello, hero :) I've created Soloing Masters chat to gather the best soloers and speedrunners of nowadays! It's for theorycraft and soloing discussion, and also I plan to organize some m+ or arena events with the whole team of soloers, it could help us to create new and epic video content :) Imagine how good 5 soloers can do this stuff if the each one can perform better than 5 people sometimes :D community link, if you're interested: blizzard.com/invite/70zXrRI3vW
