Gathering 861
Perception 862

I can confirm that all legendary nodes are now 95%/15% (I have all 3 miner books unlocked).

From my observations the threshold is 860 for gathering to be 95%. Sorry I did not pay as much attention to perception but my gut feeling is that is around 855 to be 15%.

I have all Augmented lvl 200 left hand side gear (pick axe too) and HQ IW belt, sledgehammer and accessories.

Melds are mostly to support natural 650 GP with minimal overmelds, which is all I need.
