Sorry now you're just grasping.
The hard minmaxing fact remains: offense is the best defense. Removing the foe's hit points is the goal of combat. If you play a fighter or other martial your primary job is this and nothing but this. Having feats that make you twice as good at your job, is simply unsustainable - it drastially reduces options in the game, since it is decidedly unfun to play a build that kills foes half as fast as your buddy.
Everything else is just words.
Why are you so opposed to the concept that the devs have failed to rein in the balance of a few feats?
If you're not running a combat-focused campaign where DPR matter, why oppose the idea of errataing these feats? They wreck some campaigns and don't bother others, so fixing them will stop them from disrupting the first category while still not impact the second. It's a win win situation.
You come across as someone trying everything in your power to not have to concede these feats are too good.
Why? What is so devastating about such a conclusion that makes you work so hard at avoiding it?
