Oh no it can't. Any 4e character can make one opportunity attack per turn - stopping everyone who tries to go past. Any 4e PHB fighter stops anyone moving with an opportunity attack as well as doing damage. Any 4e fighter marks whoever he attacks. Any 4e fighter gets an interrupt when a marked enemy attacks an ally. And that's with neither powers nor feats. A Pathfighter fighter can do none of this. When your fighter can't do what a 4e fighter can without either feats or powers, your claim is show to be false.
Higher level monsters are normally bigger and stronger - which means that their CMB and CMD scale faster than humanoids do.
You mean that we want things to be effective? Rather than just some vague nod that allows you to claim you can do something while being normally less effective when you use it than if you didn't?
They actually are effective, you just choose to engage in self inflicted blindness to try and make your argument valid. If you want a lockdown type of fighter in Pathfinder then you can easily do it with no problem. Now if you can't because of something personal then that's on you and not on the system.
So would you like to try and argue some more or are you just going to sit there and sing la la la while you ignore what proves your point as incorrect?
