I don't get why Expert Tracker is in the Sharpshooter Talent Tree. Otherwise, I really love this talent tree! You can do a lot with it, that's for sure.
Nowhere in the flavor text does it say that the Sharpshooter is a hunter (I kind of get this more from the Bounty Hunter's Survivalist class, or possibly some of the Explorer Classes from EotE, or the Commando or Scout specializations from Age of Rebellion). My impression is that this guy is solely focused on guns, not necessarily tracking his target through the wilderness.
I think it would make more sense with the theme of the specialization for Expert Tracker to be replaced by something like Point Blank Shot. Other thoughts?
