You get a fraction (less than 90%, surely) of the fighter's Combat Challenge and Combat Superiority features. You're still down 5 builds and like 400 maneuvers.
As a beatstick and meatshield it's just fine, it does lots of damage, every round, and is reasonably durrable.
A worthy rendition of the 2e fighter.
It's a little less worthy of the 3.5 fighter. Not so elegant, only does a few of the many possible 'builds,' via combat styles, and a few more if optional feats are used.
And it's nothing at all like the 4e fighter which was both a functional defender (sometimes argued to be the 'best' in the game) and, well, balanced with the other classes out there, even the casters.
Take battlemaster and you don't need 400 maneuvers... which were really only 200 worthwhile and often 3 or 4 did the same but some level higher.
Yes the 4e fighter was really cool. But you are puking too much value in quantity than quality.
I don't know what the 3.5 fighter really brings him close to the 5e fighter... feats? Magic items maybe? Maybe non core feats...
Did you even play the fighter in 5e?
