I am running two wow accounts so I always have access to the Auction House on my Second Monitor. This saves a ton of time and let’s me keep on top of my competition. The account is currently on a separate Battle.net account. This was necessary to get around the old token limit of 36 per 24 months. This limit is no longer in effect so I might be swapping back to the same battle.net account again.
On my main server I have the following characters on my main account:
110 Shaman (Main) Jewelcrafting/Enchanting
108 Druid Leatherworking/Tailoring
100 DK Blacksmithing/Inscription
100 Warlock Alchemy/Engineering (Vials, Sky Golems etc.)
100 Rogue Tailoring/Mining
100 Monk Alchemy (Pyrium bars)
92 Mage Enchanting/JC
90 Priest No professions
90 Hunter No professions.
My second account has two lvl 90s with alchemy for Transmutes and my Bank Alt.
