So i'm just trying to unlock grimoire cards. On the weapons side of things I'm only missing a couple of exotics (hawkmoon, thunderlord, fate of all fools, necrochasm). I know FOAF isnt available yet and I've got Eidolon's Ally waiting to be converted to the Necro. What's the best way to farm for the other two, other than Nightfall? Does VoG Templar/Atheon on Normal vs Hard modes make a difference in drop rates? I don't care that they are the weaker 300 versions, I just want the cards. How about ROC playlist? Does it even drop exotics at a decent rate?
