Thanks, JD. I aim for simple and elegant. Most of those alt.rangers don't.mmadsen, that's a great take on it too. And it's simple and fairly elegant to boot!
Some of the suggested Special Abilities might work as Bonus Feats though, e.g. Trailblazing: Wilderness Lore check to treat trackless terrain as a trail for overland travel.
I'd prefer to replace all the complex Favored Enemy schemes with a simple Foe Hunter Feat (+1 to-hit, +1 damage, Improved Crit vs. one type of enemy), as in Forgotten Realms. And frankly, it wouldn't even have to be one of the Scout's Bonus Feats -- anymore than Ambidexterity would have to be.
