how much would you pay for a large set of crafting materials (characters worth - 140+ at least), pre organized and able to come into your game and wait while you craft, feeding you materials as you need them. this would eliminate the space demands of large crafting sets as well as the time cost associated with gathering, organizing and finally actually crafting everyhting.
the example would be something like, you order 240 caster amulet sets. i gather 140 pamethysts, 140 ral runes, etc. including the magic amulets on 4 different accounts and 8 total characters, 2 per account (140+140).
i then come into your game with 4 characters at a time spaced out around town to keep drops separated and feed you crafting materials as you wish. say, 10 at a time, 40, an inventory at a time, or even entire characters worth (140 of each material at a time).
then whenever you said, "next batch" , i would drop more. this allows you to not leave things on the ground and to not have to hassle with all the inventory jenga that goes into crafting such large amounts of stuff in your own stash.
i hope you all can see where i am going with all of this, so yeah, how valuable of a service would something like this be to you?
