The CEO of Larian Studios touched on this with his gripe about Hasbro/Publishers. These studios will get rid of their knowledgeable people to earn more money at the cost of performance/creativity/problem solving, and then they end up reinventing the wheel or never solving issues. He specifically said this is why he does not want to partner with Hasbro at this time. They are making their own IP to avoid this in the future.
I have to suspect this happens in a lot of MMOs, and why we get wild swings in expansion/quest "quality". Not just DDO. But all games.
Ask yourself why it took them until Monday to get the game back up, and it was up fairly quickly, over the weekened we lost service. Almost like they had to hire a contractor to come fix things, because no one on the team is knowledgeable enough to fix whatever the issue was.
