Amen to that. I, honestly, never saw a problem with being able to pump up save DCs- if anything, it made higher levels somewhat bearable (considering battles didn't last forever with everyone making their saves). Now, not only did Wizards screw over the Spell Focus feats, they made the Spellcasting Prodigy feat SUCK big time. Not to mention that a few of the Epic feats (such as all of the feats that increase one ability score by one, or that feat that makes it so that you only have to get a 5-foot running start to make a running jump) aren't worth taking, even as non-epic feats.
YMMV, whatever that means.
