Dunno about you guys, but the main reason I prepurchased was to play early. That's money down in advance, unlike a preorder. It's not my problem if Arenanet have not provided a sufficient architecture for everyone to log in on day 1. I'll be after claiming some kinda compensation back if the headstart turns out to be a total bust.
That's not whining that's having consumer rights. If you lose even 1 day of your headstart it means you were sold something you did not get. Stick up for yourself people.
