This information is for DPS fighters in nightmare DW dungeon, with some helpful hints I've learned along the way.

PROVOKE/CONFUSE FOR LAST BOSS
Basic DPS Hints for Darkness War
You don't really need Cleanup for any of these bosses, so use a hard-hitting Elite instead. The bosses need fantastic positioning and avoidance of AOE's, so be prepared to move, a LOT.
One DPS needs to be specially prepared for the last boss with Provoke and Confuse. Unless you're trying for Master Planner, just have a build with both equipped that you can switch to for the last boss.
Batab Crusher
If the adds come to you, run to the tank and let him pick up aggro. Watch the far end for "Living Bombs" (they move slowly and have a purple halo effect, you'll see them a lot during this dungeon). Kill them ASAP with a ranged attack. Red Mist works great.
Xibalban Bloodhound
Be careful not to aggro too many adds with Supressing Fire. Let the tank pull up the adds before just randomly attacking.
Otherwise, this one is a pretty simple one for DPS. Just hit the boss hard and stay out of the filth.
Dark House Sorcerer
I love this fight. Be prepared for rapid movement and avoiding AOEs. Don't stand on the pretty patterns he makes on the ground, but be sure to quickly move IN right up to the boss when he makes the circular pattern or you'll get sucked into a fire tornado, not fun. When the tornado vanishes, move away quickly and watch for the bloody ground AOE and attack the adds. They are those stupid bugs and fairly easy to kill. Be prepared to quickly move back in towards the boss for another tornado, and remember the pretty patterns will eventually start rotating. I just take a step or two, close to boss, and halt rather than try to continuously move. During the last part be prepared also to avoid the bloody ground AOE which will leak into your "safe zone" inside the tornado.
Helpful Hint: Avoid using Supressing Fire or Red Mist during this fight. It will make it hard to move quickly in and out of the safe zones.
Unbound A'kab
This fight can be messy if the team doesn't know what they're doing. Under no circumstance should DPS be attacking the adds around the playfield. When they die, they explode and leave a deadly blood pool. Therefore, the correct way to deal with them is to allow the Tank to draw the adds to one spot--a small alley at the far end--and only when they are there should you shoot at them.
One common way DPS gets killed is when the A'Kab comes up from burrowing. To avoid this, you must watch where he's going (you will see a brown trail coming up from underground) and move, move move. He will one-shot kill you when he comes up otherwise. Other than that, just avoid his frontal cone AOE and watch out for blood.
Mayan Battle Mage
Most DPS are killed by the carpet bombing. In general, once you do it a few times this is fairly easy to avoid, but sometimes bad luck happens. However, there is a regular pattern to them. I suggest watching a video of it. You can also just try to keep towards the middle of the playfield and watch where the boss is throwing the bombs. You're basically just going to be moving from Center to Left, or from Center to right.
Help kill the adds and gather them to the tank. When they turn into Living Bombs, STAY AWAY and kill quickly with ranged attacks.
Wayeb-Xul
Last boss, yay! This can actually be a fun fight if everyone has pre-determined roles and is organized, and the Tank is aware of the importance of impairing Exhale the Void. One DPS must have Provoke/Confuse on their build. Another 1-2 DPS should be assigned to kill the Living Bombs in the final phase with ranged attacks.
The DPS with P/C equipped needs to watch closely for the boss to start "Concuss". When he does this, immediately hit Provoke. Count to 1. He will turn towards you. Hit Confuse. What this does is, it prevents him from going into an aggro wipe and from teleporting the group towards him, possibly dragging you into filth if the tank hasn't successfully impaired Exhale the Void.
The Living Bombs that start in the last phase are brutal to the team, so it's crucial to take them down. Do not get close to them. A ranged attack is a must. Many teams will assign 2 DPS to them, and have just 1 DPS stay on boss to finish him off.
