Blood of the North was the first of the Death Rune talents we implemented, largely to fill a hole in the deep Frost tree. At the time it needed to be 5 points or Frost had to backtrack a lot in order to go deeper.
But the other two trees ended up with cheaper versions of the talent and Frost has changed so much that I don't know that it needs to be 5 points any longer. This is something we might look at for 3.1.
