So for the last part of the defender subclass quest I would recommend doing a strike with lots of adds and door opening, that way people have to kil the adds. Example devils lair or summoning pits. All the other subclass quests can easily be completed in the undying mind strike, can choose that one on Playstation and hope you get it on (rumors that the strike have arrived at xbox). There is a point where you have to defend against a lot of yellow health enemies. Should be possible to make 7orb supers twice here. If you miss it here you can also get two 7orb supers in the boss room, if you dont burn the biss to fast. Hope thia helps a few people so we can avoid people running out of the strikes to kill the three hive majors in the spawning area for patrol on earth.
