After reading some on the website, I'm tempted to try to box this.

Can you run several instances on one PC like you can with WoW or is it registry tied to where you can only do one instance at a time per PC? I only have one computer, but it's more than capable of running at least 3, I would think. I do it in WoW with plenty to spare.

Also, does the in-game macro system to to be any good, or have you tried it? Does it even have one? I think I read on the forums that it does.
