There's the cheap way... Find a couple of guys with Gjallarhorn and a Titan with weapons of light... Make sure you all have full rockets and have a synth ready to go for when you're out of ammo... Start of round Titan pops weapons of light then you all unload all your rockets, pop your synths then keep shooting till he dies, If that's not an option then what you should do is have the whole team book it straight away to the left or right side of the arena to one of the defensible areas.. I prefer right side personally. Use cover and focus on taking out the adds. When the Eye of Qodron spawns you want to make sure that you don't lose sight of him, but avoid killing him until the notification comes that he's looking for his targets or unless he's in danger of moving out of sight. Once someone has the jailbreak buff you want to bunch together. I find the Icebreaker makes really short work of the detain shields. Even without having the buff the IB can get you out of the shield, and the regenerating ammo is handy. Everyone should focus special weapon fire at the shields for maximum effect. Once the ads have been cleared away then you want to focus as much Damage on the boss as possible. When Running IB in my exotic slot then I like to use a high impact heavy machine gun and put as many shots on his crit as possible as well as emptying some rounds from the IB when I can. Usually once the second wave of Ads has been dealt with you should be able to finish him off... If you don't then just keep doing what you've been doing. If you're patient, careful and communicate well with your team then this fight will be a formality...
