Ooooh boy. First one my roommate got for me, he used my Hunter to play on my profile but did Crucible almost exclusively. One day he says hey, I wanna try Nightfall. One time. Never before and never since. He gets Gally. Personally the first one that I myself earned was off the Deathsinger when I two-manned Crota a couple weeks ago. I'd say that it was hard, but I solo Crota on the reg now cuz it's such a freakin easy raid, so no I didn't earn it. However I did feel a major sense of completion and accomplishment and far less drive to grind out anything on this game anymore, which makes playing more pleasant!
