I agree with the animal companion being like a stuck on flavor thing with its effectiveness. It isnt even needed. I can see a wilderness warrior having an animal buddy, Grizzly Adams and stuff, but as far as the PHB campanion goes, its worthless in a fight. Im OK with the spells, thats D&D, but make them more useful; at the levels a ranger gets his spells they are largely worthless. Entangle at the level a ranger gets it is a almost a joke beyond rare encounters against hordes of kobolds in the outdoors. The spells that have come out after the PHB have mitigated this somewhat, though.
Ill agree again with the d8 hit die. A ranger isnt a tank, hes a fairly sneaky warrior. Full BAB, yes, needed. Lighter armor, definately. (I allow full abilites in medium armor, myself. Chain mail fits my conception of lightly armored) 6 skill points is dead on. Im even ok with the favored enemy. While it isnt perfect, it does fit the archetype, I think, as either a favored prey as a hunter, or a primary enemy as a free spirited Robin hood type. I can imagine it could be made better, but I cant think of anything better at the moment (thats why I pay people to make the games for me, I suppose

)
And the fighting style, while a step in the right direction, is still nothing but a throwback to 2E dual wielding rangers (which just completely baffled me.) Some kind of bonus feat progression in place of the fighting style, an upgraded animal companion, and a better spell list would fix things up.
I dearly loved the 1E ranger, but Im under no illusions that it made any kind of sense as a literary or mythological archetype

It was a horrible hodgepodge of abilities. Still, I would have loved to have seen a minor arcane spell progression added to the 3ED ranger, perhaps as merely an allusion to elven teachings. Magic missle would have made no less sense than two weapon fighting, but it would have had the benefit of continuity from 1E.
