I agree, there needs to be some adjustment with how these events are implemented. As I suggested on the Facebook topic (but will repost here in case it got lost among the other posts) was that you do like GW1 and have these events be reoccuring events instead of one time events. That way people don’t all come on at once causing large lags. It would stagger things out if people knew if they missed the first time they could just come back in a few hours and experience then.
You could still have the World Changing things happen. It would just be permanent at upon the last of the reoccuring events of that particular day.
