Since the release of Graymore I have noticed that the loot process has changed from what it was prior to the release. At times it seems normal, and then it just stops working. I do a lot of fishing for perfect roe, so I do my fishing where I can get loot to help pay for my time fishing. What I have found is that the loot process works for a period of time and then getting anything other that gray or green items simply stops no matter how many hours you keep working it. I filleted over 1000 fish and only got 2 perfect roe. Normally the rate is 1 per 100 fillets as a rule of thumb, but now it's 1 per 500+ fillets. This has happened to me several times, so this isn't just an abortion of the loot process.
The loot I was getting prior to Graymore compared to the loot I'm getting after Graymore has changed such that I have to put in 5+ times the effort to get the loot rewards prior to Graymore. I don't know the loot rate for a lot of other items in the game. If this is only affecting fishing it's a pain, but if this is affecting drops elsewhere in the game the prices with guild merchants are going to be changing.
