As we changed rarity in components we also adjusted how they were used in recipes. Generally speaking, basic recipes will only use common components, intermediate recipes will use common and uncommon components, and advanced recipes will use common, uncommon and rare components.

Along with the changes, buffs from crafted consumables are also getting another look to ensure players are getting enough virtual bang for their virtual buck.
