Hello everyone!
I wanted to formally iterate here what we've currently settled on in terms of our pricing for some of the items in the guild bank:
Crusader Orbs: 100g
Runed Orbs: 50g
Abyss Crystals: 10g (Now available from the withdrawl tab!)
For other items (BOE epics for example), we will continue to use our 75% discount rule for Guildies...and these prices will always be based off the lowest (reasonable) AH price.
Because demand for the first two items is usually high, and supply is limited, we recognize we will need a fair system by which people can get a chance to purchase orbs. I don't want to be spammed with whispers for orbs while I'm doing loot so the officers will take this one offline and discuss a good way to dispense these. We'll keep you posted
