I just ran through the entire vault, and opened every chest we could. I got ascendants from every single one, except for the titan mark and chatterwhite. No guns, no gear. Nothing.

I got a full set of raid gear, gjallarhorn, hawkmoon, vex, and the last word on my hard raid Tuesday, there is loot available in the raid, you just have to be lucky. I like the rng, the chance of getting nothing (happens to me a lot) and then like this time I get everything I want. Rng is a gamble, and personally I enjoy it.
