Disclaimer: there are other methods and others may disagree with ours but this is how we beat it in about 3-4 minutes. Enter the room and and stay together heading immediately right through the tunnels all the way across to the area with broken chunks of concrete looking blocks. This is where you will fight from. Once Qodron and the ads spawn each player needs to look for the precursor (silver vex from the Atheon fight) and destroy him ASAP (I cannot stress how critical this is to do fast), the person who kills him will get a timed blessing (located a smidge above your feed) which allows you to complete the next part. A message will come across your feed (above your super bar) saying "Qodron searches for a target". The whole team needs to get together at this point. A detainment shield will come over the team (have shotguns or high ROF special weapons) that you as a team must destroy (note: you take damage from the detainment while in it so group up behind cover before detainment). The blessing one member has from killing the fore mentioned precursor adds extra damage to the team for specifically destroying this detainment bubble. Once the detainment bubble is destroyed pound the hell out of Qodron with heavy (ghorns are nice but anything works, 365 exotics will do wonders). After about 10-20 seconds (maybe a hair longer) the team needs to start finding the new precursor. All enemies will come to you in this spot so stay here. They will not go up on the deck if you use grenades and basic tactics so look for the silver shiny guy in the mix and kill him fast. Also be sure to watch the left side (if facing Qodron) for enemies coming through the tunnel. Rinse & repeat until dead. Hope this helps, good luck. Bump to help others see this. Edit: apparently the one with the blessing can leave the detainment bubble, he/she can then revive the other 2 in case they cannot destroy the bubble.

It's not impossible, just keep trying.
