I would still push for D10 HD. Even if the ranger isn't a fighter subclass, s/he is still a fighter first and foremost. If s/he gets a fighting style, s/he is a fighter. Please keep the D10. Ranged combat is an option for the class, but doesn't need to be the default. A frontline class should have D10.

I'm actually liking how this is shaping up. Kane0, you may have changed my mind on the ranger being its own class! And here I was even looking to make the paladin a fighter sub (again).

I'm looking at the scout rogue class now. I personally think some of this can be folded into our new, improved ranger. The ambush master feature seems like if c/should be worked into the ranger's quarry feature. I admit, I have no qualms about "raiding" the scout for some ranger stuff: the ranger was here first!
