Looking for some significant bosses

I'm currently doing the elite hunter titles. I've done Prophecy and to add to my fun i kept Maw as the last boss on my list.

Now I,m looking for some significant bosses in NF and Faction.

For NF, i've done most of it except The Realm.
For faction, i've only capped a couple of usefull elite.

Im not looking for the hardest boss to cap from, but mostly the most "EPIC" of those 2 chapter, bosses thatare memorable or really stands outs from the rest.

Thx in advance for your suggestions.

Not sure what you mean by epic, but go here http://guildwars.wikia.com/wiki/Elite_skills_list and take a look see.

For the skill link thx, but i'm already using MappingOut to keep track of it all.

You fight the boss, you kill the boss, you take its skill.

Sorry, just never considered any "boss battles" as "epic" :/

That would be my choice for Factions. Neither are hard, both are in the same zone. I just found that zone to be the most 'adventurous' for skill capping.

Not so much the boss, but the Torment creatures and the environment made this one more 'epic' for me.

He was a pain. Glad I got that title finally

You've inspired me to go for the Elite Skill Hunter title.
I always thought of it as one of the stupidest titles ever, because many elites are useless to you, but I like the "role playing" in killing the bosses... As if you were assigned the duty to kill them all :P ... I feel silly now :P

the only factions boss that caused me any grief was mungri....(boon signet) with his bunch ----the boss being a healer and he has a healer in his group, otherwise factions was pretty easy (the ones in sunjiang were also more irritating to get, but still easy).
Nightfall....hm....before they changed things in the realm of torment some of those bosses were hard...now pfffft.

Droajam, Mage of the Sands in NF can be fairly wicked, and for a real challenge, hit him up on hard mode. You can cap Sandstorm from the Drought, too, but he isn't a challenge, so you could make it a point to take on Droajam for Sandstorm. Korr, Living Flame has potential, but nah. If you've already got those all, the only boss in Realm of Torment to give me problems was Master of Misery, simply because getting to him is a small adventure in itself, especially if you misread the map.

In Factions, Kunvie Firewing and Star Ancient Koosun can be difficult if you don't have a good party makeup, but they are a far cry from Droajam, let alone trekking to Maw. Factions was pretty easy to cap in, unfortunately, and I doubt either of those will measure up.

Edit: Oops, like my information is out of date. Master of Misery and Consort of Ruin swapped places, so Consort of Ruin is the tough one to get to now.

The NF boss with Order of Undeath is mighty difficult to kill, even in NM. I felt proud after finally getting him.

Thx all for your replies. I' ll look those up and keep you posted.
