I'm just wondering, because I'm thinking about planning to make an Assassin's Handbook, unless there already is one. I also think they should get Hunter's Eye (you know, SA dice =1/3 CL? That's not overpowered for someone who's normal CL caps at 10. And it would be useful and flavorful. Grumble.)
The fact that the ranger get's such nice things (Hunter's Mercy, Hunter's Eye, and the like) makes me believe that our friendly neighborhood rangers are actually bounty hunters, trained to track down and kill pretty much anything.
I knew there was a reason for Favored Enemy...
