There are some feats that give +1 attack and damage for specific things, but the damage generally does not grow as you advance in tier. This means that you get the benefits of Expertise and Focus in the heroic tier, but then either take an additional feat when you hit paragon tier, or take Focus eventually, ending up in the same place as someone who spent the same two feats for the same two advantages.I just checked the character builder, and that must be the one you're referring to.
If memory serves, though, there WAS a feat that was +1 attack and damage. I'm sure of it.
An example would be Hellfire Blood. +1 attack and damage with Fear and Fire powers. But its conditional (fire and fear only), doesn't grow with tier, and doesn't stack with much.
