About the Erudite:
I went to the Complete Psionic when someone said it was there. What I found out was exactly what you said "sky", I compared them (Erudite x Psion) to Wizard and Sorcerer, because that's just how they work.
I'll bring this issue now because we just started talking about it and I had a doubt... what do they mean by Unique Powers? Does that mean using the same power another time? When they gain more uses of Unique Powers, does that mean the Erudite can use more than one power twice, or just they can repeat any power they have already used another time?
I mean,
3 Unique Powers = powerA (x2) + powerB (x2) + powerC (x2)
OR
3 Unique Powers = powerA (x3)
OR
both?
I hope I was clear enough, because that's confusing xD
[this post probably needs to be moved, but as we were talking about it here, I just went on o_o]
