Global is the only one who does this. None of the asia-specifc servers do this, they sell it for silver.
We've been asking for it in the weekly Velia Inn streams and they are constantly ignored and silenced.
Come on PA, orange craftable ring but requirement is to be in a guild with a T2 node? Smaller guilds don't have access to that and the ones who do are already full of whales who don't need it. Yellow and higher grade accessories are more essential now more than ever for CP, and you lock it further into content that demands higher CP. What's the point of progression when it's fragmented like this?
Or give us more chances to earn black pearls easier to obtain said accessories :D
