Every MMO launch I've experienced has been similar to this, at launch there is a lot of excitement about the game and everyone wants to see what the excitement is all about. SE never expected such a positive response to this game, since 1.0 blew up in their faces. It will take a couple weeks to get things sorted out. In the next two days they are going to revamp the hardware of the servers. If that isn't enough, they are discussing implementing an auto log out for idle people to keep free slots available on the servers. Don't forget many people will play till the end of their free month and then call it quits because they decide it isn't enough to hold their interest long term and will go back to another game or stalk the next upcoming release.
