Q u o t e: You participated in buying items off the RMAH. You removed money from the ingame economy to RL, and then moved RL money into the game economy. If you're obviously willing to utilize the RMAH why are you so opposed of playing with other players who use the RMAH?
Just to be clear: I have no issues with the RMAH or people who use it. I'm just playing a little devil's advocate as it were.
However, I'm taking issue with some of your statements. "You removed money from the ingame economy to RL, and then moved RL money into the game economy is something I'm a little confused by. What you're talking about IS an economy. Think about it this way: Rename your regional AH currency (dollars/pounds/euros etc) to something you'd normally find an a game; credits for example. When you load up your wallet with cash, you gain the credits and can spend and trade with them as you please. It's only when you "cash out" that the credits become currency. I'm hoping you can visualize how we're just looking at an alternative in-game currency. What you need to remember is that this "economy" doesn't merely consist of people who load seed it with their mastercard and others who make a profit. There will be plenty of people who take part in neither and who really are just treating it like a second in-game currency.
