Urgoz in HM

Well today's bounty is Urgoz, and me and 2 guildies, possibly a 3rd plan to do it later tonight with heroes. Our problem is, we've never done it in HM. I run a Warrior, my brother runs and Elementalist and the other is a Ritualist. The fourth possible would be an Assassin. We can all run anything and can setup heroes in any way. All I'm looking for is some tips on specific areas, or any other useful tips. Thank you to anyone that can provide anything (I have already read the wiki, I'm just looking for some more tips.).

My alliance routinely completes this in Hard Mode, and it's not really much harder than Normal Mode. There are only a few additional things to consider:
Monsters' additional movement speed requires more careful pulling to avoid wipes. Hopping Vampires also move faster, so bringing Recall can help keep your DP down while triggering these. Underground roaming groups trigger more quickly unless you are carefully pulling, so pull back to the start of the room!
It's really not much harder, good luck!

The dual room with exhaustion+Weakness tends to also be easier, as you can pull further, and spike down the environmental monsters from below.
But other than that it's basically same difference between NM and HM

I'd also like to join if you want a noob
