I've been having a lot of fun, and good success, with this build:
I'm at work, but I know communing is high, and Spawning and Channeling are moderate, and I have 5 points in Domination.
Rt/Me (Luxon)
Ritual Lord
Boon of Creation
Backfire
Channeled Strike
Shatter Enchantments
Disenchantment
Shelter
Union
First, not nearly enough people bring enchant removal, and Kurziks bond the architect like 80 % of the time.
Mission start:
Kurziks either go for mines or fall back. Either way, Boon, RL, Shelter Union just out of Kurzik Elementalist's range.
Kill mine rushers if needed. Then go for first gate.
Cast Backfire on one of three guards. They all cast, so it doesn't really matter which, but I always go ele because he protects the group. Follow Backfire with Channeled Strike, which gets the ele casting at -67 per spell. A turtle shot and a little wanding and you're in.
Lure assassins out, but don't let them get to you, kite around teammates/Luzon warriors. Once they're dead, go for Ranger. Remember to redrop Shelter/Union as needed.
When you reach the second gate, look for enchantments on one of the guards. Disenchant if needed, and hit the caster with Backfire. It's not deadly with 5 points, but most monks/mesmers WILL NOT cast with it on. Necros are 50/50 and eles never even see it.
Kill Guards, then try to make yourself small. By that, I mean do not attract attention to yourself. This is the hardest part for a squishy, with all the Kurziks and human players who have been waiting for you. Just drop shelter/union in a corner and hit someone with Backfire/Channeled strike. (I find the followup channeled strike can elicit a cast even from a human player).
Once most of the NPCs aere down, focus on the final gate guards/Juggernaut. With the gate open, I drop S/U if needed, target the architect and just tap Shatter enchant to auto run to him and cast. Then I drop Disenchantment. Then I usually die. But my job is done
Run back for another round of S/U and Disenchant if needed. If you get targeted, you'll probably die again, but if most of the Kurziks are involved with your teammates, focus on the architect with everything you have.
