Having gone back there I did get some good stuff I dont know if the update has played a part in it but try for your self.
I was their just the other day. It was getting crazy full out war for 15 ish minutes. http://youtu.be/B0wcdrWBEZ0
I don't understand why people want to use a "loot cave". It was amazing before but now it's not worth it. You actually get more engrams from tiger strikes (24) than you do from loot caves now
hes right tiger strikes are by far the most effieciant way of getting engrams these days plus it does your vanguard marks and rep no harm .... actually much more fun than stood in one spot shooting the same hole for hours too
