Did it twice this week: Two Titans and a Hunter = easy peasy. WoL bubble in front of skanks door, barrage of arc sniper shots to Skolas' head. Critting is obviously necessary. Immediately after the first bubble expires, another goes up. Specific mine spawns are crucial. C is preferable, since the whole group can remain together instead of having to send the Hunter away to A or B. Disintegrate Skolas, disable the remaining mines, dance, then go collect your garbage rewards from the chest.
