My strategy is to start by going left when you come out, destroy that servitor then shoot Skolas as much as possible, then you run around to the right (or your left if your facing Skolas) to the platform on the otherside, if all three of you go there you can hold that spot and not take too much damage. You'll die from splash damage occasionally but as long as you clear off the dregs and vandals you should be ok. Then just proceeded to shoot him until the mines, and send out one of your team (Hunter or warlock with self res) to disarm them.
