This is what I did last night. Had 4 bounties for earth and need spinmetal for upgrades s i I made my way to the cave everyone's been ranting about and it did not dissapoint. Resulted in two ranks up on cryptarch which ended up giving me an exotic rocket launcher and legendary Warlock helmet. There were about 4 of us at one point which allowed me to do things around the house while wracking up XP and Engrams. IMO drops shouldn't come from lvl3 hive when your lvl 20+ Drop rate should increase and quality of drops when going up against mobs that are higher level than you. Defeats the purpose of earning your rewards
