I usually do combine the usefull with the needed. Like I always run these material hunts with bounties each day I start playing or when the Vanguard resets. Why all you tutorial makers NEVER mention to combine the bounty mission with these farms? Example 1: Spin metal farm in the Cosmodrome where also a bunch of hive spawn for the Hive kill bounty AND 3 Fallen Majors near the locked down DLC entrance in the Cosmodrome. Not to mention doing all this together with the 6 patrol mission bounty or the 200 shards collecting mission one "yellow" Vandal gives 25 shards x3. More then one fly with one hit. Example 2: Relic Iron... Same as with the Spin metal there is the area in the Burried City part where two or three Vex Majors spawn for the 200 shard Vex mission, 10 Vex major kills, etc. The chest spawns there are much more tighter together with a ton of Relic iron aswell. There is like 10 fast respawn chest spots, 10 rare ones (aprox 1to 5 hour respawn windows). PS: In the spin metal one you forgot to mention two possible chest spawns in the huge "tubes", behind one of the trains. and on the small building near the room you forgot to check twice in the video.
