They've pretty much already said the classes are being phased out and branching jobs of the same role are an extremely limited variety. Let's not also forget the reason for Bards doing less damage to begin with was not only due to support options but also mobility. So it would be reasonable to say that a ranger would also have lower damage and without any viable utility it would never compete with Bard.or Machinist. Without damage it would never compete with the casters. As the others have pointed out is that it wouldn't really fix any issues or bring any substantial changes to the game. making it a waste of development time.
