OK, you’re right, if everyone would have n votes and the votes would have a unique priority 1…n, then the picture could shift. In the current state, if everyone votes for the top 5 points, it is not clear, which of the ones is the most important overall. You only see, that every of these points is more or less important. So it is a tendency, that is presented.
The DAM will be extended over the years, so that it will reach a state, where it could become usefull for some people. As stated by DxO here: Wow- Have i missed something?
