Ultimate Combat introduced the Trophy Hunter archetype for rangers. It focuses on and implies firearm use, like the Holy Gun and Spellslinger archetypes. Unlike those, however, it doesn't get the Exotic Weapons Proficiency: Firearms or Gunsmithing feats which are both necessary for firearm use or the starting gun. There are several threads on the forums which discuss it and all agree that it SHOULD have them (with most house-ruling it), but no answer from anyone in Paizo to address the issue which, considering some of these threads are over a year old, is a little disappointing.
Based on the character concept of playing a proper english gentleman game hunter (like Van Pelt from Jumanji), I thought the Trophy Hunter would be perfect. Unfortunately, it becomes pointless if I've then either got to waste a level on gunslinger or burn my first 2 feats and 1200 gp to make it happen like it's supposed to.
It would be REALLY nice to get something from Paizo on this (or a link to errata if it exists) so that I can take it and use it in game.
