I understand the frustration, I feel it too sometimes. But the title you chose doesn't encourage constructive feedback, and is inaccurate as far as I can tell.
The fact is that any work is subject to a conflict between time and quality. In the case of DE, they have to find a compromise between polishing every aspect of the game and creating new content. It was shown in many fields that the curve isn't linear at all, like in the example below.
If DE polish too much they will take too long and lose too many players. If they create new content every week it will be unplayable and they'll lose players. So they chose to release new content regularly and focus on fixing only the things that we complain the most about. They don't "love" this situation, but that's the best they can do. Actually they're pretty good at finding a balance.
With that in mind, every time I'm having fun but get frustrated by something that is not polished enough, I remind myself that it's a sign of a healthy free-to-play game, as weird as it sounds.
