• We keep the current Feat -> Improved Feat -> Greater Feat -> Perfect Feat paradigm
  • The first three feats provide a sliding amount of bonus.
  • The fourth feat provides a bonus that scales with level/BAB/skill/caster level, as appropriate.

That way, the feat tax keeps the non-martials out of the cool stuff at Perfect Feat, but the Perfect Feat scales appropriately, giving the fighter the cool stuff he needs to be competitive at high levels.
