Almost all spells scale with caster level, in terms of range, duration, and/or damage. Fighters get fewer feats than spellcasters get spells, yet their combat feats almost universally do not scale, or scale with things that have nothing to do with BAB (such as Dodge giving +2 if Acrobatics has 10 ranks). Instead, they are forced to invest in "feat chains," generally rendering several of their class features (feats) obsolete. This situation is bizarrely lopsided in favor of casters at higher levels, contributing to warrior-class obsolescence syndrome.
I would like to very strongly urge that combat feats be revised so as to scale with BAB (analogous to the way spells scale with caster level). For example:
Dodge
Prerequisites: BAB +1
Benefit: As long as you retain your Dex bonus to AC, you receive a +1 dodge bonus to AC. For every 4 points of your base attack bonus, this dodge bonus increases by +1, to a maximum of +6 at BAB +20.
