Since the nerf to Ursan, Cry of Pain has become a favorite skill of mine. I like to use it with Warriors having Sentinel armor, since you can create a build that includes "Save Yourselves", and do huge amounts of damage while greatly helping to protect the party. To top it off, you can sustain your own energy level adequately. The following build is one I have used extensively to do DOA, Vanquishing, and HM missions:
[build prof=W/Me name="W/Me" box Str=12+1 Inspiration=11 Illusion=8 desc="Weapon #1: Staff +20 Energy +30 Health"][Auspicious Incantation][Conjure Nightmare][Echo][Cry of Pain][Web of Disruption][Leech Signet][Ether Signet]["Save Yourselves"][/build]
It's an easy and fun build, letting two W/Me's target the same or different foes in a group, with the knockout punches being 4 Cries of Pain delivered in very short time proximity. The build has two hexes to fuel COP, 3 energy recovery skills and 3 interrupts (4 counting COP twice). Quite effective. Add a couple MM's, a fire Ele, a Mesmer and a couple of monks and you can roll thru many challenges comfortably.
So I'm just wondering how this build would hold up in Urgoz one day and I decide to enter the mission for kicks (Party of 8/12). After re-reading through the excellent guide on wiki (http://guildwars.wikia.com/wiki/Urgoz%27s_Warren), I go into the Warren and Wow, I'm actually hanging tough with these foes. I was extra careful to pull only ONE mob at a time, and before I knew it I was at the room with the locked gate, right before the fire bridge. Time - 32 minutes. Then I realized I couldn't progress any further because no real player had Necrotic/Consume Corpse to get to the Gate Locks. D'oh! - You used to be able to rez a dead party member onto the bridge with rebirth, but no more. Also on this first attempt (and several subsequent tries) I was using 2 1/2 MM's (2 full MM's and the Blood Rit Necro). This was fast in the early stages, but turned out to be slower by the time I got to the Warden room, as I couldn't keep the minions alive and kill fast enough to support all those heroes needs. I actually made it to Urgoz with this 2 1/2 MM build one time, but then botched killing him as a bunch of heroes got trapped in some spores and EOE did a party wipe ACK!
After tweaking the builds some to compromise between mob killing and spike damaging Urgoz, I made about 3 more attempts before succeeding. I decided on Grenth's Balance for Team 1 War because you have to have a Necro profession on a real player. Then I decided to bring Symbiosis along and have each Monk hero equip a persistent enchant. This worked great as I was able to get up around 900 HP, let Urgoz and the Explosive spores damage me down to about 350, then use Grenth's on him. Also having Ebon Vanguard Sniper Support was quite handy, as the 10% chance sniper mass damage triggered once for each Warrior. Team 2 War was able to echo Sniper in addition to Cry of Pain, which was great. The heroes weren't all that useful against Urgoz. I tried to get Backfire, Chaos Storm, Meteor Shower on Urgoz, but practically every time I tried to get a hero close enough, they ended up dying and it became a headache to get everyone rezzed. At one point both real players were down and I had to get them up with heroes YIKES! The two Warrior builds plus EOE are entirely adequate to kill Urgoz without additional help.
Here are the builds I used:

Each party member had a proper attribute +15/20 energy +30/60 HP staff, except Team 1 N/R (Blood Rit Necro), who I elected to give a +5e +20% ench sword, and -2 damage +45 HP while ench shield. This set kept Team 1 N/R alive better because he often had to run into melee harm's way to deliver Blood Rit.

Success!:


I used some buffs after the fire bridge up to Urgoz, and they ran out while fighting him. We took about a 15 min break after getting to Urgoz, so total time about 3 hours. There were many hard fought battles and several real close calls - the kinds of things that make this game fun (when you prevail of course!)
All in all it was great fun and a very rewarding victory!
