My first vault of glass we did it legit, and not knowing how it worked.... took us nearly 8 hours to complete it, but it was certainly the most fun I have ever had in a game. Crota's end.... haaaa what a disapointment. So full of glitch that you end up cheesing without even trying to (like the self rez at the bridge....). So boring that after the first one we end up glitching the hell out of it anytime we enter it just to get some armor piece to reach max level. And it's still totally glitch nowdays......
