Compared with, say, oh, I don't know... ToughnessToughness... this featthis feat seems to cover the same territory (assuming a feat every two levels) pretty exactly, but you absolutely have to take psionic feats to keep up. Now, you can, of course, take both (although Toughness isn't a psionic feat, of course), but what about for the psion who doesn't (flavourfully) want to take Toughness? Seems to me like the rules would be improved if you could only take one or the other, but Psionic Body gave, say, three hit points per psionic feat.
Thoughts?
