Hardest raid/boss

[Barael]

My all time favourite is original Lady Vashj. If memory serves it was only killed 3 times before substantial nerfs (they removed a whole mind control mechanic from the fight) one of those kills was bugged.

Archimonde...never in my life have I seen so many players getting killed on a boss so much because of "lagg" on the tear.

I didnt do ICC HM nor Firelands HM so this goes out of the way.

We spent on lot of time on Hardmode Mimiron, so many things to watch, total chaos . Good times ^^.

[Ryme]

Deemed impossible.

I'm sure I saw a cheeky couple of sub 5% wipes, I reckon he was killable.

[Dungeonravor]

Heroic Lich King 25 was a pain especially with 4 times a Guild Master switch.

[Resentful]

I'm sure I saw a cheeky couple of sub 5% wipes, I reckon he was killable.

5% Is huge like that's like not even a kill right there you know how brutal that shit was pre-nerfed? Friends crying again and again and again wiping to the same % over and over

Like they overtuned that fight so god dam bad haha

1-2% isn't even a kill

It's what I've learned the entire hardcore raiding of my entire career granted some bosses die within 1% aka Yogg. My point is a low % doesn't mean It's killable especially how overturned that fight was ''apparently''

[Libertarian]

Vanilla: Ragnaros, Vaelastrasz (8 priest woo), Nefarian, C'thun, Four Horsemen

Yeah, I do get it, it came across as if the first kill would have been done by luck and not perfect execution - still, I doubt he was impossible.

[Vashi]

Kael prenerf for sure. Spent 3 months on him before we killed it.

Sarth 25 3D. Spent a lot of time there, that was for sure a really good fight.

[FF]

Personally, it was Kael'Thas. 8 weeks, 4 nights a week, 4 hours a night

[Deleted]

Definitely Ragnaros HC before any of the nerfs.

[lappee]

Hahahaha I keep forgetting ahhh an honorable mention

''Heroic Vizier'' - Heart of Fear pre-nerfed

Deemed impossible.

it was possible, the nerf just came in way too quickly.

Yeah, it just means that the raid need more gear, and this progressive and natural nerf should have been enough. My former guild and I brought him only a dozens of time on p4 before the nerf and I can't even imagine the frustration of those who were a few percents close to kill it.

[Deleted]

Putricide was rough at 5%-10%. Those diseases... ugh

I still have nightmares of that freaking buff lol, OUT OF MELEE OUT OF MELEE OHH FUCK... :P

[Capell]

Heroic Vizier took us about 80 trys and made me pretty mad dying with no orbs at me at all...

[Deleted]

Kael prenerf for sure. Spent 3 months on him before we killed it.

Sarth 25 3D. Spent a lot of time there, that was for sure a really good fight.

While I agree it was a fun fight...it wasn't hard. But it was a rare fight where a lot of class utility was used...I think it was one of the last even where all class utility was used to that level.

[Keoren]

how overturned that fight was ''apparently''

One of the most annoying things about the encounter from what I can remember was the way he used his abilities in the final phase. At best I think we saw almost a 10% health difference in how soon he spawned the first echo. Variance happened with the second one as well.

Lich King Heroic. +1000 wipes. I know, we're bad, but we have never before og ever since had the same trouble with a boss.

[Butler to Baby Sloths]

Vanilla - Four Horseman and Cthun are the hardest bosses in the game during current progression. Hands down.
BC - Muru
WOTLK - Professor Putracide And or Yogg 0 lights
Cata - 25 spine and Sinestra
MoP - so far H iron Quon just because were currently wiping non stop.

Overall - The Illidan Queue timer gets my vote. 4000+ in queue and a 2 hour wait.

C'thun was technically impossible until he was fixed (he died within an hour of the fix going live).

[Mikael123]

25 man heroic Lich King. I think it took us close to 200 wipes before we got him. I was tanking. Killing him is among my best memories of WoW.
