If cost is the issue, I would have rather just invited a bunch of the American commentators (Steadfast, feardragon, Beomulf, catz, etc.) That would have been a better decision.
I saw Wardi and Nathanias making good points how this brings down other costs (hotel, bringing production staff, etc.), but then I would have rather ESL just not have a Dreamhack Atlanta then. Don't know if I'm alone in that opinion, esp. speaking as an American.
