Robe and Bone armor requiring, from the lower lvl, enchanting mats to make was not a good choice. Now you have one variable impacting multiple aspects of the game.Kobold bone is now too easy to get (outputting 400 kobold bones an hour in a good spawn currently, which is nuts). Giant bone is way too hard, considering you ALSO need a good chunk of thick leather to go with it. And that's hitting enchanters too...(And in the meanwhile, staff recipes are still not fixed and r80s are way cheaper than anything above r40s).
Agree on the Flesh Golem nerf. It felt wrong. The mob was super easy and dropped way too many Giant Bone for that difficulty and respawn timer.
It's not 2-4 bone. It's 2-4 bone for someone with 0 skinning, 20 wisdom and no Skinning Title. For someone maxed with title it'll be 5 average per skin. But even though it's an easy mob, I think it's new loot is too light when compared to a comparable slow-spawn MOB like the Crog.
