Thanks niknight - yes I'm aware the level 21 feat was also changed to scale into epic levels.
I was just making a comparison for the old/new versions of the level 26 feat because it wasn't clear whether if the slight damage buff was intended to occur for both feats or just overall (assuming players take both).
In case the intention was to increase damage (besides adding scaling) for both feats, I wanted to point out that the new feat actually dips in damage at 26 (4d4, avg 10) when compared with the old feat (4d6, avg 14), although obviously it comes out slightly ahead at 30 (6d4, avg 15).
