I don't think the Priority levels are too influenced by how easy they are to accomplish. It just happens that accessibility really is not all that hard. There are plenty of videos that are useless without audio description. For videos of that kind, the audio description is a Level 1 priority. Audio descriptions in many instances would be unnecessary, so those are Priority 3. I don't thing we can write the guidelines to define when audio descriptions are necessary, let alone define what constitutes "good" audio description. The current tools and technology (Real / SMIL anyway) makes converting a transcript into synchronized captions trivially easy, so I don't see the advantage to saying that a transcript meets A while captions are only neccessary for AA.
