I like to have psionics as an option and like that we got psionic powers that target the int saving throw.
Which brings me to my greatest concern: the psionic sorcerer has no int saving throw proficiency, while the wizard does. So it is easier to attack a psion with psionic spells than a wizard. I think it should be vice versa.
On the other hand, I am not sure how it was in 2e. I remember that it somehow was easier to attack psionic characters with psionics back then, but I found it strange there too.
I hope the 5 defensive psionic powers make it in too.
