Qilin shouts are in abundant on my server and has had quite the effect on HMP. Atm there's so many of them out there prices have actually fallen below 100k. And basically have made finding riftdross and Cinder's a lot harder to come by.
It would be a nice bonus to see them added to the other mob's to encourage more shout's for those VW fight's. But I'm thinking balance has been obtain atm because of the huge available on plates. And the fact that cinder and dross is harder to come by is probably the way the Dev's would like it to be.
