I've played almost 200 hours and I've only just got enough etheric light and armour cores to get two characters to level 34. I got one etheric light from a nightfall, and the rest from PoE. I would be all for a slight increase in getting it. Or even just a chance at getting it from more locations. I do like the grind, but I'd love to get some of my favourite weapons fully upgraded before TTK drops. Edit: I don't usually get much of a chance to play weekends so I can't do the trials.
