[Meta] BAB prerequisite for feats - 1, 4, 6, 8 and 11

[Locworks]

I'm trying to map out the underlying principles for weapon-related feats to help me nail down the prerequisites for some combat maneuver feats.

I've done it up to BAB +11, but I'm struggling with some areas. If you're into this sort of thing, I'd be happy to read your advice.

BAB +1
- minimal skill level
- reference melee/ranged feat: Weapon Focus
- reference melee feat: ?
- reference ranged feat: Point Blank Shot

BAB +4
- confirmed skill level
- reference melee/ranged feat: Weapon Specialization
- reference melee feat: Great Cleave
- reference ranged feat: ?

BAB +6
- first iterative attack
- reference melee/ranged feat: ?
- reference melee feat: Improved Two-Weapon Fighting
- reference ranged feat: Manyshot

BAB +8
- ? (just because it's between 6 and 11?)
- reference melee/ranged feat: Improved Critical
- reference melee feat: Stunning Fist?
- reference ranged feat: n/a

BAB +11
- second iterative attack
- reference melee/ranged feat: ?
- reference melee feat: Greater Two-Weapon Fighting
- reference ranged feat: Improved Precise Shot

1 Weapon Finese
4 Spring Attack
6 Whirlwind Attack (no one can take Spring and Whirlwind at the same time at BAB4)
8 Greater Weapon Focus
8 Stunning Fist

Personally I don't think there's a pattern.

the +4 and +8 bab prereqs are so fighters can get those feats before anyone else. Otherwise they may as well be bab +6 and +9 repectively

Ryn, who has always considered this a fighter class ability ;)

Can you point me to any feat out there with a +9 requirement?

[SirUrza]

I think his point was that fighters get feats at level 4 and 8 (when they have the qualifying BAB.) Everyone else has to wait until level 6 and 9 to get feats... BAB or not being the issue.
