CleverNickName said:I think the most sacred cow of psionics is that it is different from magic, and immune to many of the things that suppress magic (yet having its own set of things that suppress psi power.) As long as this Most Holy Bovine is kept in 4E, I think fans of psionics will be pleased.
And I second what Enforcer said about reducing the science overlap. Absolutely.
I'm a big fan of psionics, but this is what I would hope for:
Look at Rolemaster and see how they break down their spellcasters. They have essence (wizards), channeling (clerics), and mentalism (should-be-psionics). Each has strengths and weaknesses, but they're pretty transparent. The only difference is the power source and certain effects are easier for the different types of caster. I'd like to see basic telepathy to be a trivial effect for a psion, as an example, but much more difficult for clerics and wizards--maybe even limited to one-way until extremely high power levels.
I do have to admit, though, a certain fondness for the psicrystals. As this is imbuing a construct with sentience, maybe you say that it's fairly easy for psionic users while more difficult for divine and arcane casters.
