Some of the Advanced Classes seem a little unbalanced to me. When you consider that the Core rules only gives the +1/level BAB to one Advanced Class and that's a melee specialist the you have to question the "Dead Shot" (a ranged specialist), "Enforcer" and "Bounty Hunter", the Enforcer isn't too bad.
I worry a bit about the the Bounty Hunter gets the best BAB, one Good and Two average (no poor) saves, average Defense bonus, decent hit dice, and skill points. There doesn't seem to be any drawback to this class, other than tougher than most entry requirements, but as many D20 designers have said before entry requirements don't provide balance, they just mean an already advantaged character can take the class.
You have to wonder why the designers of the original game didn't give the Soldier or Gunslinger the +1/level BAB progression, there was probably a reason to keep that for the more melee focused classes. For this reason Enforcer isn't really a problem, as he seems to be more of a melee sort, but the "Dead Shot" raises an eye brow from me.
Not only does "Dead Shot" get the best BAB, but only one poor save, okay it has a poor Defense bonus, but by second level thanks to the class abilities, it has a total of +5 attack bonus (+2 BAB, +2 circumstance from Dead Aim, +1 Weapon Focus), later on they get another +2 to attack rolls thanks to class abilities. This is ment to be balanced by a poor defense bonus and poor skill points, but if the game is at all combat focused, then this class will shine. It also does seem very well thought out, while most Advanced Class will be getting a cool unique ability at 10th level the "Dead Shot" gets a feat nearly anyone else could purchase at first level, and would be much more suited to early on in the characters development.
