I didnt say monsters, now did I? Fighter/Ranger/Barbarian etc ability, gained at BAB 6... make 2 attacks as a standard action. At +11, 3, etc. Whirlwind attack sure as hell should be a standard action as well.
Or make all non healing/defensive spells over 3rd level take multiple full round actions to cast and fatigue, then exhaust casters. Casters should sort of suck in combat anyways, since they can completely dominate non-combat through utility magic
Either way you slice it, full attacks suck in their current implementation for keeping melee equal to casters/ranged characters. Pathfinder could have easily fixed this through feats/class abilities, but didnt.
So, let's take a class with the worst selection of armor and weapons, the worst BAB progression and the worst hit dice..... and make them WORSE in combat. Yeah, that'll show them for having Knock on their spell list.

Full attacks by melee-optimized characters are capable of dishing out triple digit damage, something tha all but the most tricked out spells cannot do. And swords don't use charges or spell slots. The greatsword weilding, power attacking fighter can swing that sword every round all day long, something casters can't match under a Vancian system. It's fine.
And finally, you have no clue what is in the Pathfinder RPG core rules. Already some feats have been previewed that address some issues with the fighter class, but until the final document is released and in our hands, you just can't say what they did or did not "fix".
