Well.. for starters, those are games by different studios within BioWare. Then consider that ME2 was extremely successful, and DA2 was still a success (and still a good game) in spite of its failings - failings caused by a rushed production cycle, which this game has hardly had. Your argument seems misaimed to me. The beta was more polished than most release MMOs I've played.
All-in-all, your comment's a wild tangent that's not really relevant to the discussion.
