Since many players already have most of their uniques, the mats drop got increased for some parts they become almost worthless which makes refining eclipse caskets pretty useless(sometimes out of 50boxes ppl drop just 30 assembleds, 10gems, 3 new ashtals, 3 combi stones lvl1-4, 3 new scions and not even 1item worth more than 100m) . This makes eclipse farming almost useless.
My suggestion:
Lower the amount of assembled artifacts from tesslons
Lower the rate of assembled artifacts in caskets
Increase rare drop in caskets
Lower refine cost of caskets or increase gold drop in eclipse
Everyone with good arguments is welcome to arguing.
