For those complaining about the drop rate, I dont see how its been a problem I just got my 7th one tonight :D
EDIT 1: This is Satire obviously, I run regularly with my clan, we had 4 people that had not gotten the Vex drop yet, myself and another received duplicate drops. I'm at the highest drop rate with 7 now, how can this be a possibility? Looking at you #Bungie.
