Hey,
The Juggling torchs Juggling Torch - Item - World of Warcraft used for the achievement to juggle 40 torches within 15 seconds, is one of those achievements that can be done at any time; you do not have to be in Midsummer event, also the items are not BOP or have a duration.
The only safeguard Blizzard has implanted to stop people from exploiting these in the Auction House is to make them unique, however you only need 10 or so to complete the achievement, meaning that if you only get one pack; you can still sell 4 stacks for a high price once this item is no longer attainable.
However, in order to maximise profits; I suggest using a trick around the unique problem; Unique items are only unique when they are on your charater, in the auction house or in the bank; not in the mail. Remeber these are not binded to you, you can mail these one by one to an alt then just return them, if you don't return them; you'll get them back in 30 days, which is likely when these will sell the best.
The reset has made this into a very vaiable method of making gold, if you are like me and already have everything from Midsummer; you can, from today visit all fires again and get 5-10 blossoms (aka 5-10 torchs) per fire visit AND the 6 or 13 gold per fire hand in, including the capital cities for 25 each.
Hope this helps someone! :wave:
