I would move this over to feedback so the bungie team can see it

Everyone needs to focus fire on skolas and not stop until he is dead. Mines take only a few seconds to dismantle. We had our first mine across the map. We focus fired to kill skolas then all ran to first mine. A good strategy is for 2 ppl to fire with ghally while one fires with high impact sniper. Then switch once the heavy runs out for those two players.
