Your Exp with Psi-Chars

[Spatula]

What does everyone think of these house rules based on your experience with psionics?
* Get rid of multiple ability dependency and make psionic effectiveness depend on Int or Wis (probably Wis).
* Make bonus PPs depend on Con.
* Remove psi attacks and use Mindscapes, slightly modified.
* Use the PP progression from Mindscapes for the Psion.
* Use the known powers progression from Mindscapes for the Psion.
* Use the "psionics is different" caveat.

Am I setting myself up for a game-breaking character?

So you'd be nixing the bonus feats that the Mindscapes psion gets?

I agree with Nifft that a better solution to MAD is to redefine the abilities tied to each discipline - although I personally would move Psychometabolism to Con instead of Charisma.

I'm a little leery of 'psionics is different' myself. If you're just using stock monsters and NPCs, they won't be able to defend against psi powers. And any psions in the party won't be able to defend against magic spells.
