I just made psions a sorcerer variant. (I have three: outsider- blood, dragon-blood, and psion) It seemed to make more sense that way. Cause well, in the PsiH thats really what they are except that they have special psionic vs psionic attacks. You scrap those and what do you have? Essentially a sorcerer that specializes, so why not just have a sorcerer? Besides, psions really get shafted as they cant use thier abilities as often. Granted they should come up with a spell that simulates the Mind Blast, but so many spells are common tricks found in psionic fiction that it works.
Psionics does not make sense unless you are doing a psionics are different variant and you use a lot of psionics in your game. I don't really.
It will be interesting to see what bruce does with it.
