This is pretty easy when you know the trick.
A good thing would be to have 2 ranged DPS to take care of adds. One could do the job, but best with 2.
There are 6 candles inside the room. 3 on each side. 2 of them is right beside Vexallus, 2 is a little longer away from him (Around 30 yards away from him), and the last 2 is very long from him.
Let the ranged DPS stand VERY close to a candle each. Actually have them stand inside the candle. They have to stand between the candle and the wall. They need to be so close they actually allmost get stuck between the wall and the candle. The ranged DPS should NOT MOVE AT ALL during this fight.
When this is done, start pulling Vexallus down to the stairs, otherwise the ranged DPS cant hit him. When adds spawn (at 85%, 70%, 55%, 40%, 25% and 10%), let the ranged DPS kill them (use instant spells as the adds deal 2000 damage every second to the whole party).
If this is done correctly, the debuff from the adds will show for about 1 sec, and then disappear. If this doesnt work, either the ranged DPSs arent standing close enough, or else they properly moved and then this trick wont work.
Turns out for some reason the candles disspells the debuff.
When doing this, the only thing you have to worry about is the tanks health and the Overload. But with a good healer, this is no problem.
Hope this helps you!!
