Their response is uh...deflecting at best. The connection is dropped and re-established on the server end every 15 minutes. I don't know if that's leftover jank from 1.0 or what, but I can't think of a reason a login server would need to do that. Furthermore, it's wild that it doesn't try again even once when the connection doesn't re-establish, and then it boots you from the client entirely. It's pretty egregious that they didn't address this once they knew congestion would be an issue.
