Fighters still can dish out alot of damange more so then in 3.5 , with the new crit feats ya can build one that crits with say a longsword on 17 auto confirms and blinds anyone he hits with a crit, or do bleed damage or both at once
The first time you can take Critical focus is level 9. That's a +4 to confirm critical hits. In order to take Bleeding Critical you have to be level 11.
A rogue is using a weapon with a wide crit range because they're relying on being able to get crit damage and SA. A Fighter is going for the best base damage and/or crit multiplier.
The Rogue can start inflicting Bleed at level 2. At level 11, they're doing a guaranteed 6 points of Bleed damage with no need to score a critical like the Fighter.
And every single one of those Critical Feats? A Rogue can take 'em too. Assuming they don't just take Bleed, Combat Trick (gain a bonus Combat feat), and Crippling strike and decide they're better at the whole Critical thing than the crappy Fighter critical feats.
And the Rogue still gets to be the skill monkey, do UMD stuff, and ninja around half-invisible.
If the Fighter's job is to absorb hits? They suck. They can't stand there for very long just soaking up damage. They have to rely on others (cleric) to keep them going. If the Fighter's job is to inflict damage, they suck because the Rogue can do a better job overall and avoid an awful lot of the spells that come their direction to boot, while busting out magic as an augment if need be.
The issue isn't _just_ can the fighter take some extra feats to do more damage? Because the answer is "Yes. And so can every other class too."
The other point also was, "Why take out this feat chain?" It was kinda crappy, sure but it still gave a fighter a chance to dish some big damage. Now that chance is further removed (+4 to rolls to confirm a critical) and all the "great" critical effects are using BaB as an attempt to block other classes from getting them but by the time a Fighter or anyone else can get them they're having a negligible impace on combat; at least that's the way it seems to me based on how combats have been going in the Pathfinder AP and running an 11th level fighter right now.
