I actually like the way there is no separate US/EU 'zone' and that if we really want to we can play on US servers, or US players on EU servers, but it would be good to have separate EU/US admin so that there is proper EU timezone support. Hopefully it's something they will introduce in the future.
It does seem odd that there is a good 6 hour 'dead zone' between the start of the working day in EU and the release of the first EGA wave of the day. Surely it would have been in their best interests to release, say, 6 waves a day (one every 4 hours) with users equally shared between EU & US.
Ah well, I'm at work today anyway so it doesn't really affect me but it still seems odd.
