Let's talk about the Vanguard and faction drops. Your light level might be 370 for example, but your gear might not be balanced. I had items dropped for a lower light level than the ones I have equipped (My "superman cape" (Hunters cloak) for example is 372, I got two consecutive drops of 370, and no damn boots which I so badly need). RNG hates me in a bad way. And unfortunately I am not the only one. 2 people of my team had some excellent drops and are past 380 now. Me and 6 others played as much, if not more than them, and we got stuck with RNG at 374 and below.
