To be clear, there is no excuse for bad service at launch.
"Servers are getting hammered" just means "We didn't want to pay for the servers to cover launch surge, we'd rather spec our server farm for our average concurrency in week three and save a ton of money."
You can say a lot about Destiny and Bungie and how this game is going to kill both, but they launched mostly flawlessly with no major service interruptions on day 1. It can be done.
All true. They just cheaper out.
