Hardest boss to cap experiences

Maw is the only hard boss to cap, period. The Sunjiang bosses can be semi-hard to cap, but it's mostly just a matter of knowing the path to not aggro 10 mobs at once in getting to them.

All the Fire Mission bosses like Goss are very easy to cap. Beating the fort or the titans with Heroes/Hench is a cakewalk.

Not sure why so many people had a hard time with Mungri, he's a cakewalk too.

Legendary Skill Hunter mostly only shows time/money committment, not skill; since pretty much all the caps are extremely easy.

non of the elites are really HARD to cap but easily the most annoying is maw getting FoC but that only because it takes time to reach him!

My experience:
Bohdabi the Destructive (Order of Undeath)
Bazzr Dustwing (VwK)

There are harder bosses like bosses that have a chance to spawn in missions or are at the end of a mission. Or the Tyrian bosses that share a spawning point. However, when you reach them, they are easy to take down. And I think all or most mission bosses have a counterpart in an explorable area.

Maw is easy u can run from rankor zone and then solo kill on Rit dang i love my rit lol

The 2 toughest for me on my ranger while acheiving Legendary Skill Hunter were:

Power Flux from Vision of Depair in Domain of Pain, can you say oversized group.

Onslaught from Onslaught of Terror in Nightfallen Jahai.

QFT cus henchies just love to aggro everything in that massive room ¬¬.

On top of that golden skull strike was pretty hard because mobs wander close to each other and always manage to attack together >.< .

Agreed. Along with this, the construct must have an ungodly amount of energy as he psychic distracts about EVERY spell. My paragon has Legendary skill hunter and this was the only cap that took me to 60 dp. I hate this guy. If I had a mesmer elite tome, I would have rather unlocked with Balt faction and used it on that skill.

Without a doubt.
Legendary Skill Hunter title SHOWN PROUDLY OFF!

.... that bastard monk boss that has Healer's Covenant

Every other guy, when you buckle down and put your mind to it is actually pretty freakin easy. But man, that mofo can heal

I was worried about Consort of Ruin.
Easy.

Also think the LB title DID play a part especially because heroes share it.
So Rank 6 might have helped me blow through the guys.

The ones I found difficult were:

Mursaat Boss for Aura of Faith in the Ice Floe.
Maw the Mountain Heart for Feast of Corruption in Dreadnaught's Drift.
Abaddon's Mouth, just for the repetition when the boss doesn't spawn, sometimes 3 times in a row.

Mungri Magicbox for Boon Signet in Ferndale.

Josinq the Whisperer for Healer's Boon in Resplendent Makuun.
Master of Misery for Jagged Bones in Depths of Madness.

These bosses just caused more problems for me than any others did.

Maw the mountain heart is not that hard, just takes a long while walking.
Spindle, Plexes and Goss are kind of the same, kind of hard to reach, but not that hard, as they spawn most of the time.

Snake Dance only skills Earth Shaker and Punishing shot I capped when I was lucky. I got them both on the place closest to deldrimor war camp. It were 2 short runs and i was very happy not needing to go to the spawn place near dreads.

Mungri magicbox is one of the bosses that caused trouble to me, because of all the patrols, and he and his gardener are hard to kill, daze is a good solution. Same goes for the healer's boon Boss. Daze is needed.

Realm of Torment Bosses are hard to kill in my opinion.
I also find bosses in the frozen forest kind of hard to cap, like Virulence.
Most other bosses are easy

omfg, sorry, the page didn't load so I was punching the keys..

Mungri Frickin' Magicbox.

That is all.

WTS SoJ!

But seriously. Healer's Boon was a bit hard to get. I got em on the third try from changing my build from Healer to Protection to Smiting >.>

Another notable cap is the Shield of Judgement. Really. It took FOREVER to find a group and someone had the Titan Source quest active >.>

My guildies at the time helped me after I cursed out Anet on the guild chat for a while >.>

Korshek the Immolated...duuhhhh...Searing Flames!

I did it with henchies...it was so hummilating...took me 3 runs to finally cap it.

NEVER EVER AGAIN!

MAW I did twice once with my ranger (for the heroes) and again for my Necro to get all her spells. Was in exactly the same place both times.
Abbadons is just a pain because of the random spawns but is very easy to do with heroes and henchman, but I quite like doing PuG's there.
The Ranger one in Domain was hard because of the size of the groups, but I got his green bow there. I have capped all Rt, Ranger, Monk, Necro and Ele elites. Still have to do Paragon, Dervish, Warrior, Mesmer and Assassin. The wiki is really good when doing this.

Vision of Despair (Power Flux) in the Domain of Pain.

When I go capping, I usually don't plan ahead but just grab a cap sig and off I go with whatever is on my bar and whichever H/H I have at the time, and I always forget what a pain this boss is. Usually after a couple full-party wipes, I wish I had planned ahead better and brought different skills or a different party...especially when I haven't killed any of his group yet, but instead they are multiplying through Call to the Torment because the H/H have decided they don't want to follow my calls anymore. Anyway, he is my least favorite to cap. His group is tougher than most. Ouch.

Droajam, Mage of the Sands~For Sandstorm...don't know what it is about him but it took a few times.

Maw took 2x because she died from degen underground...learned the hard way about that little bonus (capped it about 2 years ago.)

Most Irritating Elites in Tyria, random spawns=farm code or botlike activity...ugh!

The only one that really gave me trouble was Restore Conditions from Spindle Agonyvein for my monk. I had to do that damnable mission 14 times before the boss spawned. This was before Factions even, and I went with PUG bonus groups every time. Of course, just to mock me, the boss spawned every time on all my other characters, and has spawned every single time since for my monk.
