I've noticed that even when on the sweet spot, you have a tendency to hit materials other than what your are looking for. To illustrate my point, I was logging in Skull Valley aiming for ash branches for the GC quota this week, I am a lv 38 btn. At that level, my gear shouldn't be an issue, and I would think that I would be guaranteed a high chance of getting the mats I want. (if not a 100% chance) Instead, I'm getting large quantities of cock feathers and ash logs, pretty much everything but the ash branches I'm aiming for. What gives?
