If events are your major concern, then I'd suggest attempting to gather a few people interested in making events in "EU time" (which I assume to be GMT, CET, and EET.. Perhaps GMT -1). If it is simple interaction, then I wouldn't worry, so far there have been plenty of "EU player here" comments in the various threads, so we seem to be plenty, if not united as of yet.. And apparently not vocal enough for those who share your concerns to be at ease.
