One problem with DLCs is that they dilute the consistent idea or style that might have been implemented in the main game. And the entire model stimulates developers to do that, as it's cheaper to make more of what you already have, instead of making something new with a separate consistent vision. So they usually look like a fifth leg on a dog, and break the style or balance in the otherwise solid game, and that's the consequence of the model itself. Even if the DLC is good it can feel disproportionate to the rest of the game. Good DLCs for good games are... scarce.
