Those shadow bosses are just sadistic. They are generally what wipes me out in Tiers 60-65. Havent been able to get past 65 yet.
However, the sharpshooter tags me with a 1 shot sometimes and that stupid lizard that spews green projectiles at you constantly for like 7 seconds…you have to run in a circle or dodge quick and hope the shadow boss doesnt tag you while you’re doing that. It kinda becomes a souls like game for most players above T 60. But thats probably intended.
I have not seen the most annoying sharpshooter in my last 15 runs. I suspect Blizzard quietly pulled him off the roster.
Blood Bishop because having to stop what am I doing to target specific areas of the arena to avoid what is probably a OHK while random OHKs and danger zones from the shadow bosses are around is a terrible “mechanic.”
Once Bramble had the entire arena covered with poison except for a tiny sliver on the side opposite me when a shadow boss went off. Wasn’t pretty.
The…bug guy…just the pools of slowing poison everywhere.
I mean…none of the bosses are that bad, but the wrong combo of shadow bosses/floor color/vision destroying trees or pillars can turn things into a nightmare quickly.
Seahag does seem to have the lowest life, surprisingly.
As a barb, I simply change one of my skills to include “Iron Skin” and with all the cooldowns I have, Iron Skin is only off for about 3 seconds before I can use it again.
Only issue with that is you can’t use Iron Skin until you have life missing. So if you’re one-shot, you’re screwed. Have to use after using shout which hopefully mitigates the damage enough to almost spam Iron Skin.
How do you know when it’s sea-hag / leave a pit run? Just teleport out before she can kill you? I’m scared of her more than any others and I play hardcore 
I’m playing barb this season and beat her all the time. She has a pretty limited number of attacks. Are you standing next to her when she’s doing her water pool explosions or something?
gave me flashbacks, had to share

Its outlaw sharpshooter by a large margin and then sea hag.
Outlaw you just dont know what to do. I as sorc just spam fireshield as much as I can with ice armor and dodge randomly while on top of his face and it seems to work most the time.
Sea hag just is beefy with many otks as well. I dont spam fireshield here and am getting better timing it for just the 1 shots as you can sort of tell when they are coming. I have no idea how to do this vs outlaw. He just gibs you out of nowhere.
As a Melee any of them that shot-gun-firebolts… which in melee means they all pretty much hit you since they all have the same starting point.
Some bosses are ‘better’ to have over others -I have yet to reset a zone due to a particular boss though.
Finally see people mentioning the Drowned Seahag, plus all the echoes that appear on fights.
I can deal with the hag the most. Wolf a close 2nd. Sharp shooter is annoying for me cause of the whirlwinds. The ghost specter is annoying cause it feels tanky for some reason compared to the others and it gets the worst echoes you have to dodge.
I think we can all agree outlaw is the worstest! Book of Eli skillbar.
Outlaw be like 
Sharpshooter. hands down.
Followed by Frozen shaman.
Literally, all of them.
Lazy
Rehash copy & paste design. Blizz designers are shameless.
Hate the Outlaw Sharpshooter the most. Too many shadow bosses. The second one is the Seahag. The rest I have no issue.
If you really paying attention you would notice that the shadow bosses when Outlaw the boss do more damage too. Not sure if he is buffing them which is unfair since we can not debuff them. Or it is a bug but it is VERY obvious the shadow bosses doing more damage. Get one shot by things like the goatman which barely scratch you normally.
What? She’s extra thick, both literally and figuratively, in my experience.
Den Mother on the other hand is noticeably squishier than other bosses.
Sharpshooter by far you fight him 5 seconds > Red patern one shot appears then he disappear comes back 3-4 seconds red thing patern again and it goes on and on it’s just awful
I personally find the Sea Hag most annoying. She does this “Splash” attack that shoots from the ground really quickly and it can sometimes 1 hit KO you.
SPL0000SH !!!
Dont hate any of them. But when I see sharpshooter at the end of the pit I go ‘eek!’ He is the only boss to give me trouble atm. I farm pit 45. The other bosses at that level i can take. But its 50/50 for sharpshooter.
