weapons of light bubble, middle of the opposite side of room from valus, everyone has 7 gjallys to start. wait for initial salvo from mcdickface. pop the bubble, (weapons of light, illuminated & bastion) get blast shield medal, test him with primary to make sure he's no longer immune then one exits each side (ie left and right) one jumps, everyone unloads 7 rockets, then stand in bubble and pops synth, and repeat can help to have 2 titans, so you can repop bubble if it runs out. if he's not down from that split up and finish him with snipers/ primaries from each side. edit: when they nerf his health 30% this method will be proper easy mode, althoguh pretty easy anyway
