I actually found 3e psionics worse than 2e because it was too much like spells. They even had the 9 levels of powers. I don't need it to be like 2e but I'd rather something different than 3e.Being that I'm familiar overall with psionics since 2e, I have the general opinion that 3.5e psionics were the best and 2e psionics were the worse. So I'm definitely of the opinion that it shouldn't be too different from spells.
Still I don't like the psionic tradition wizard, that should certainly go back to the drawing board, and the others could have some more versatility in options.
