Ahhh. OK. That's gotta be pretty annoying.
I support your reasoning here. Being a prerequisite doesn't make a feat good. Having prerequisites can make a feat less good though, because the cost of taking it can come to be more than the value it actually gives.
Yep. Crafting is one of the more campaign dependent things one can (try to) do.
That's because Point Blank Shot is a terrible, terrible feat that is worse than Weapon Focus. Weapon Focus!
Every archer has that feat because they're required to have that feat to get access to things like Precise Shot so they can shoot into melee or Rapid Shot so they can get off more shots in a round without having 2 levels in Ranger.
