Here is my GR92 clear using LoN FoK. Got a pretty nice conduit with 4 elites and a risky shield pylon that could have ended badly. Had about 4 min for Saxtris. Rank 7 NA at the time of the clear.

Apologies for the couple freezes, shadowplay was playing up. During the freeze at 6:36 I killed the 2 blue packs and grabbed the conduit to kill the other 2.
