Characters get 10 GENERAL feats.
Fighters get 11 COMBAT feats.
Rangers get 6 feats + skip pre reqs.
Barbs get 10 Rage Powers. Note: Rage Powers scale. Combat feats don't. Rage powers are like feats, squared.
Even Wizards get 5 feats.
Those 11 Combat feats of a fighter are meant to compare to the class features of every other class.
Your character's general feats compare to the general feats of every other class, so are excluded from this comparison.
And feats do NOT measure up. Just look at the closest equivalent...rage powers. Rage powers scale. Scaling Nat AC. Scaling Damage bonuses. Scaling AC vs missiles. Scaling dodge AC. Scaling Skill bonuses. Scale, scale, scale.
For combat feats to scale...you have to take ANOTHER FEAT? right.
The advanced training and x Mastery feats basically blatantly made up what fighters should have had all along...powerful feats that required fighter class abilities as pre reqs. Many of them scale, and also start out powerfully.
That's what you should be aiming for. Not more niche superspecialized feats in feat trees that fighters do NOT have the feats to spare to take.
