you mean assassination rogue? is it really worse than subtle rogue?
As for my worse M+ build: shadow priests for damage, disc for healer, and a try hard beastmaster hunter who claims they can tank with their twin bears but second bears die hunter feigns and blames the healer
They are somewhat rare now days and good ones play with friends while ones that are still learning pug would be my guess. Also they have short fuse and bail dungeons when things are not 100% smooth lol.
Go to the heaviest interrupt dungeon
Bring:
Brew
Resto druid
3x boomies
UH, FDK, BM
Holy priest
Brew
3 augs and 2 more augs.
5 of any healer.
4 drop after the key starts.
Hahaha
I think there is a youtube video out there of a group trying this. In a Nelth***(cant spell)
Bear druid with triple Aug was pushing 700kdps on some big pulls
Assuming archetype roles must be fufilled:
Veng DH
Mistwalker Monk
Rogue (any spec)
Rogue (any spec)
Rogue (any spec)
No group buff cohesion, no shared utility, limited on-demand CC, not enough dispels to help with Afflicted, no bloodlust, no stat-based buffs (i.e. fort, etc).
Then on top of all three rogues clogging Melee doing zero-point-five dps, you’ve got a Mistwalker sitting in melee clogging up AoEs as well trying to “fist weave”.
That is my plan all along muahaha 
All this on a spiteful week as well.
Tank: Prot War
Heals: MW Monk
DPS1: Sin Rogue
DPS2: Frost DK
DPS3: Arms War
Resto Bard
Desto Necromancer
Batman
Whatever toon Mila Kunis plays
Shauly Pore NPC
What I find most interesting is that tanks are finally pretty well balanced if you look at their straight ability to mitigate damage and heal that up. If you stripped cleanses and group healing from the other tanks, or better yet, gave each tank a cleanse and utility heal then we’d be in a real fun spot. Warriors are still stupid strong (they helped echo win their TGP weekend) and have no trouble with high keys. It’s silly how affixes this season have relegated several strong classes to the back just because of utility.
Disc Priest is like…unironically the second best healer atm for m+?
Sad part is no matter how bad of a comp you think you can come up with, that comp would still be able to do +20 keys easily with decent players
Community perception would say otherwise
All this thread has done is show how misunderstood monks are. Good BrMs are amazing tanks, and MWs rock. Problem is there are many mediocre ones that make the class look bad. Truth be told, I’ve seen far more bad Prot Pallys then brew monks.
Not on GD, where doing damage as a healer is the worst thing ever conceived
With some important qualifiers:
-FOTM reroller guardian not specced into raze and not pressing ironfur
-Healer new to disc and to m+ running higher keys
-Forever Ret main who tunnel-visions hard
-Tab-target-happy BM hunter
-Competent shadow priest (someone has to know how badly that run is going for it to be a true nightmare)
No brez
No lust
No locks for cookies
Minimal interrupts
No mass dispel / PI
Hard to pick.
