Look America is not getting stiffed, the largest proportion of the player base is based in the US so their 1st priority is you guys, heck look at the competitions, primarily exclusive to the US. How do you think this leaves the non-US player base feeling? I know why they do it competition laws across countries are nightmare to manage, but it still leaves a sour taste, I can tell you.
I'm still trying to workout why Bioware don't stagger maintenance though, this would Bioware a heads up any major patch related issues and time to elevate them for the greater proportion of the player base (no matter who they stick as the 1st to be patched). Heck it would also reduce the stress on staff as there's less to juggle all at once, less juggling fewer instance's of Murphyonic chaos.
