Celestrial Brew is really fun, but the shield last just not long enough for it to even have an impact on anything, and the shield amount is also really bad for the work put into getting 10 stacks even.
And getting there is a really, really long process.
I loved all three films a lot. 
Lol no, that Mage got deleted instantly lol that wasnt something the healer was gonna be able to save short of BoP or LoH
Maybe this would help? I keep one leveled up and run low keys with them to see if something will click with new changes here and there but they never do.
To me, i think its having to rely on stagger for the majority of mitigation whereas my other tanks have their own abilities that i can press where and when i want and stop the damage up front
Brewmaster? More like bruh-master. Ha!
Typical drunkard brewmaster. 
From the perspective of a healer, Brew definitely requires too much babysitting compared to the other tanks while offering nothing to the group in return. They really need some kind of defensive m+ buff.
He would have had to BoP him, but yeah. The mage misplayed it by not being in melee and the mobs living too long ultimately caused the wipe.
I find the whole thing really odd though. It’s obvious to people like me who’ve quite literally never touched the spec that it needs a ton a help and has for a long time, yet they let it go. Kudos to you for sticking with Brew for so long despite how bad it’s been.
Clearly the only solution is to delete Monks.
I’m literally only playing it to bring Mystic Touch for the raid. I switched to it at the start of Shadowlands when our Mistweaver switched to Resto Shaman.
Since then, most of the time we don’t have a Windwalker or Mistweaver even on the roster, so it makes sense for me to stick with this until they finally share the buffs/debuffs (like they ended up doing in Wrath) or remove them again.
I feel like the Mage floorpoving as soon as they press their CDs is a bigger problem than the Brewmaster being weak.
Like, yes, Brew’s lackluster, but I think this pull going this badly was almost entirely on the mage not being smart about their positioning.
