This is really small, but I've discovered a small movement optimization...

If you roll into a resource (medicinal herb, ridgewood), and your roll ends just short of the resource (need to test this more, it's not 100% reliable yet) you can press triangle to pick up the resource without the pick-up animation. The roll animation cancels the pick-up one. Perhaps there's even a way to work this into the run-slide-roll movement people have discovered; it would save precious seconds to stop, pickup a resource, and regain speed.

Let me know if you guys can replicate this!
