Done it this way three times so far with the method's inventor, Marblesmadness. Works like a charm!

1 - Break chains
2 - Go underneath the right safe platform (where the servitor and captain spawn). This will be your base for the remainder of the fight.
Poison passing method (!!!) - person who is to take poison sits in the corner closest to the center of the map. The other two kill adds. When it's time to pass poison, run to the safe corner, swap poison, then swap new person to the safe corner. The only thing to beware of down there are the captains that spawn occasionally. There will only be one captain per respawn, but it is essential to take him/her down fast. Watch radar because they can/will cause deaths. The two that are shooting adds need to be a little careful not to draw Skolas fire towards the safe corner -- splash damage hurts!
3 - Kill everything except skolas
4 - Get skolas to just above 50% health, rotate to left safe zone, hit skolas to under 50%, defuse mines
5 - Go back underneath right safe platform
6 - Kill everything except skolas
7 - Get skolas to just above 25% health, rotate to left safe zone, nuke skolas till he's dead (15-20 rockets or so should do it). Ignore adds that spawn when killing skolas. Defuse mines!
8 - Collect meager rewards

I'm happy to teach this method this week on XBONE after 10pm PT. Full runs take just under an hour now.
