I really like the rework of favored enemy. I might incorporate it into my campaigns if anyone talks about going ranger. I think the combat style part is... interesting... if difficult to read. I think straight out making a list like "Combat Expertise, Improved Unarmed Strike, Point Blank Shot, Power Attack, Two-Weapon Fighting" or the like would make things much easier to read and understand.
I like this idea. Kind of like how Scout works, but in a possibly decent class. Blind-fight is good and all, but something like scent would add to Track's usefulness. Not sure how being a hunter would allow you to follow your nose to an enemy, but something like it would be neat.
