i was bored...... so i gave it a go. it actually works cause they spawn almost constantly. this would definitely work for the "kill 10 fallen majors". you get yellow bar dregs, vandals, and shanks a LOT. and it would take about 3 minutes tops. however - the drops suck. i managed to stick it out for 45 minutes - until i was bored out of my mind. got about 10 green engrams which i didn't pick up and 2 blue (both were low level armors). just doesn't make sense to do this anymore. you could run strikes and probably do 3 to 4 in the same time and are guaranteed more engrams than this. the Roc strikes i usually get about 6 or 7 blues if i run 3 strikes.
