Two questions:

For a hunter is mailbox use permitted in order to store ammo? IE: you purchase ammo on your speedrunning toon and send it to yourself, so you can draw from your stockpile in locations that have no ammo vendor

There are some quests that require the purchase of player-made items to complete. Will the run be valid if you spend money from your speedrunning toon on the AH to buy these items? EG: A quest requires you to turn in bracers that are made by a blacksmith. You use your speedrunning toon's money to purchase them on the AH

We would have to make many exceptions for certain things if we would allow that. So to keep the rules simple, no to both. I guess ammo is a hunter disadvantage, but all classes have those :) And you can ofc either skip those quests that require player-made items, or make them yourself. There are few of those quests and afaik they are not really worth it exp wise :)

Cheers Tamlord, I just wanted to double check in case I could get away with it :) Thanks for the clarification!
