The way the fight in the naggy portal works is this.
On pull, the warlord receives a buff from the magus that gives him 97% dmg reduction. The magus therefor must be killed first. Every 25% the magus emotes "Yes!!! Let your destruction flow into me..." which signals the start of a recording buff which records all damage done to him. When this buff drops, he emotes "Too much power... I can hold it no longer!" at which point all of the recorded damage is reflected back at you in a spell called Magmal Wrath. This can result in hundreds of thousands of damage being reflected back. The magus heals back any damage done to him while the recording buff is active, but he has virtually no HP otherwise and burns down very fast inbetween buff cycles. The obvious way to get around this is to simply stop attacking every 25% when the magus emotes and wait for the 2nd emote signaling the end of the recording and burn to the next 25% marker. Its basically pointless to attack the warlord either while the magus is up unless you have a way around the 97% damage reduction. Once the magus is down however, the killing the warlord is a simple matter.

Ah, that clarifies a lot. It was very frantic when my group finally managed to defeat the encounter, and I had died from the huge Magus nuke right before he died, so I took the best guess that I could at what was happening.
Thanks, going to add that into the page. Much appreciated! :)
