I'll try to contest it. There's no reason to assume they'd need all hands on deck just to make adjustments to old quests. The game is made by multiple teams and most of them wouldn't need to be involved at all in the process. Also there's no rush to get those changes made by a certain date. They don't need to have a bunch of employees making adjustments instead of working on new content, they could just have one guy work on it for a year or two. Instead of their current plan of having no people work on it ever.
