S.E. screwed up, we know that. Get over it.
What did you expect? Early Release expansion for one of the largest MMO games out there. It is like Black Friday for nerds, get a grip, wait it out.
Throwing a tantrum and demanding Yoshi P. to step down or demand compensation and saying, "it's totally unacceptable."
The only legitimate complaints are the people that are locked out of their character.
I even saw someone asking S.E. what they are supposed to do since they can't do the MSQ due to the bottleneck.
Here is a novel idea, go outside, read a book, go to the movies, hang out with friends or family. Go to the beach, to the mall, go play paintball, go to the arcade, go play laser tag or ride go-karts. Play another game? Continue leveling jobs through FATE/PotD.
Oh no! You D/C'd? Take a break, do some stretching, walk your dog. Watch Netflix. Call your mom.
Seriously, if you didn't see this coming as a buyer, you don't have much experience with MMO games.
