DDO where every major expansion gets it's own crafting system that does not build on the previous crafting system and requires farming all new materials making the previous systems obsolete.
I like my Cannith crafting. Beside how is dino bone weapons better than Blueshine, Cold Iron, mage Steel, Adamantine, etc.?
Weapons of bone stop being used once forging is discovered by a society. Think the dino theme was pushed a little to far in this respect.
