An hour and a half at Oryx (HM) was reasonable or good when max light was 320. I've spent nearly 3 hours at Oryx CP without success back then. I had PTSD from all the blinding flashes and whiteouts when whole Fireteam was annihilated, AGAIN It became easier with April Update allowing so many paths to 335 you could go back to it already at max. Now it is very very easy and the Shade is killable in a short time before half the fireteam are inside But I still remember how my stomach used to churn at Sisters on 2nd or 3rd cycle hoping it wouldn't be me that was torn
