Oh this is a good question. Yesterday when I introduced you to my bank alt I mentioned that the bling she was sporting was original, that set has been with my bankers from the very beginning.
Now I’m on my third server since I started playing WoW. I originally started playing on US-Maelstrom because that’s where my friend was playing, and when he moved to US-Shadowmoon for better PvP opportunities I followed suite. After my raiding guild on Shadowmoon blew up (and my friend having left the game) I went to US-Stormrage for better raiding opportunities. Due to a bunch of reasons I never got back into raiding, but that’s why I made the move (and I don’t regret it, Stormrage is a good server for me).
So obviously I made a new bank alt every time I switched servers (it’s a bit silly to take the time and money to bring a level one bank alt over) but what about other times? Well, outside of server transfers I’ve changed bankers three or four times, depending on how you count.
When I first started out making gold on Maelstrom I just used a forgotten hunter alt, Rhoymarcus I think, as my bank alt. I eventually decided I wanted to be more “professional” so I made a fresh level one character (I think it was a priest) as my first true bank alt.
Skip ahead to Shadowmoon and my heroic raiding experience. I was in a heroic raiding guild and at least one other person in the guild was into gold making. He’d noticed me doing mass prospecting and gem cutting I guess and was curious as to who my banker was. I made a slip one night that cost me my identity, after a raid I sent a BoE to my banker and put it on the Auction House. That was just the slip the guy needed, and busted my “secret identity.” I ditched that banker and rolled a new one which lasted me to the end of my stay on Shadowmoon.
Somewhere along there though I dabbled in a second account. While I had the second account I decided to make use of it and put my banker on it so I could bank and play the game at the same time (along with a whole host of other benefits to having a banker on a second account). When I cancelled the second account I went back to my original banker I believe, so I don’t know how you’d count that, three? Four? Four changes technically, but three bankers.
