Just a recommendation- do 'dry runs' instead of waiting for the cool down on heavy synth. You can usually get all your rockets (usually from the servitors) before the cool down is done, and it's good practice to just screw around and play with the mechanics, plus you might find something new too. When my team and I did it, skolas kept teleporting on top of us every time, so camping in the left hand corner wasn't an option, we had to find another way to do it. And running dry runs we ironed out a strategy, had more fun than waiting in the airlock, and actually almost beat him a couple times without heavy, just screwing around. I personally think it's stupid to have the final fight be spawn killing a boss. I hope they change the buffs next week so there's new strategy for this fight.
