UW Normal Not a SC Needing some help.

Me and a few friends have been trying to do Underworld normal for awhile now, we keep taking different approaches toward certain areas, but we cannot do Servants of Grenth. We've been doing this quest over and over and just cant get it done, we can get to this quest normally in about 21 minutes. This is the build I run on my warrior(If I used the decoder right) http://www.gwpvx.com/Special:PvXDeco...ame=&Go=Submit With runes I have 9 strength and 12 swordsmanship (I made this build so Im sure there could be better ones out there) And not sure why it brings up the Rit skill pain. The skill I have on my bar is pain inverter = /

We've only got about 3-4 actual players the rest heroes. Normally we got another warrior running another 100 blades with a mark of pain as well. Normally have a Monk that changes between a Spirit Spammer or a UA Healer. The other ones is a monk as well, he goes either smite or heals, depending if the first monk takes his dervish instead. I would link their builds but I don't have them saved. We normally Take a minnion master with Aura of the Lich(mainly cause nobody has a better one.) Then normally the Discord Triple necro and add in a mesmer.

Back to my point of this post. If anyone has any better builds for a warrior or any of the professions I listed or of heros(or different heroes you think would be better) that you find to be very helpful, Id love to have them, feel free to message me in game if you rather. Thanks all.
