EU. I'd actually been assuming that the server choice was region locked like Starcraft 2 is. Is this not the case?
Being in South Africa, the distance to servers and our terrible infrastructure makes lag an issue.Since the Internets goes through Europe on its way to the US, I'll be playing EU. D2 was never really playable on b.net from here (by my standards), but I've gathered from other people that the AL is pretty good, and I've also played PoE without a problem.
