I’ve also been running Ancient Vaults because the standard mobs in Vault are replaced by goblins in Ancient Vault, but the Odious Collectors still haven’t dropped the Aughild’s pattern yet.
None of this addresses the underlying issue which is that the PTR is for us to test builds / new items. The more time we have to spend getting the recipes for crafted items needed to test those builds the less time we have to test the builds.
If Blizzard gave us the recipes up-front in a cache, they’d get more testing results which is, presumably, why they want us on the PTR.
