It's not that hard. Two basic starts I use are one everyone gjallahorn up with full rockets and have Heavy synth ready. As soon as you walk out have a titan pop weapons of light then just hammer him with rockets. For this way you need to be 34 with maxed gjallahorn's for it to work effectively. Second strat is everyone rush to the left from the start and hold that area. If a member goes down don't revive them until the bubbles are engaged so they will not be trapped. You should have a decent line of sight to him from here to hit him with snipers and rockets. Try to time killing the eyes with him getting ready to summon the bubbles. This way jailbreaker doesn't run out before you have time to pop the bubbles.
