I was doing Favor in the hinterlands today I have yet to pop a node from a favor.
First i thought it was bad RNG but i had another person tested it and seem to be getting the same problem nothing popping i used up 2 MIN and 1 BTN is anybody else having this problem today.
"Working as intended" :P
But in all seriousness, I'm not surprised. The favor system is a tedious chore and not getting anything in 3 attempts appears to be a normal occurrence, based on what I've seen people report about their frequency.
Less and less people even bother with endgame gathering and crafting as the weeks wear on.
