I would say there are three groups of Dread buyers. You have those that do not care about the rating of the animal. They only want a dread to have a dread, or they do not know about rating a dread. These people will generally pay 150 for any dread. Then you have PvPers that want high hit points for survival and if it hits hard that is a bonus. Then you have collectors that are looking at the rating and collect Dreads based on it. Each individual group prices Dreads a different way. I am sure there are anomalies in each of these groups and different interpretations. But to say the rating does not matter is to not take into account all people who buy dreads.
