Shadow Theory (d20 Modern Horror)

[The Anarresti]

I was thinking, for the Empathy psionic feat, that the DC should increase by +1 for every HD the target has beyond first, or something similar. It should be harder to read more powerful creatures. Maybe you add the Wisdom modifier of an unwilling creature to the DC? Basically, I don't why it is just as hard to read the mind of the dog sitting next to your left as it is to read the mind of the master occultist to your right.
EDIT: And, as an idea (which you do not have to include,) I wonder what you think of doubling the ability point cost of psionics and removing the sanity cost? (Telepathy would cost 2 Cha). The idea being, by depending purely on your own mind, you burn your own resources a lot faster, but you do not expose yourself to the Otherworld, so you do not loose sanity. How do you think that pans out in affecting playstyle/ balance?
