I have tried all the ones mentioned here and on Youtube, I have been farming for 4 days for a legendary engram to drop, I have had several blues and a ton of greens, and then I got lucky and got 2 legendary engrams drop. I then went to the Cryptarch for him to give me 1 coin and a blue lvl 18, and I have blue lvl 20 gear on :S I know we should not expect to get great gear within a week of game release, but when you see players in full Legendary and the 1 exotic it kinda makes farming a bit tiresome. I am now stuck on lvl 23 with no legendary gear in sight, I am building my rep up with the vanguard to get some gear not far off lvl 2 now. Time to lvl another char I think.
