I did that glimmer farming method that was floating around yesterday when I got home last night.
Spent about two hours. Got about 40,000 glimmer. Wasn't even enough to get my cryptarch to the next level (and he was about a quarter of the way through before I even started farming.) Went to Nexus farm for the last 2 blue's I needed to push the cryptarch into the next level. Got my blues in about 5 minutes. Upgraded cryptarch, package from post master.... two blue Helmets.... and one turned into a green helmet.
Two and a hour hours of my life wasted.
Went into crucible FFA, third match got a purple engram. It stayed purple, but not for my class. Oh well, at least I can save it for when I start another class.
All of these farming methods don't give me shit. I make my money in the crucible, thats about it. And thats where I've gotten my only legendary weapon.
