I got it now and I have to say overall it is way better than the previous books. Still I have some problems. The discipline powers are a good idea but I think poorly implimented. For telepathy there are too many of the things I'd conisder basic telepathy powers that all psions and wilders should have access to. I mean powers that are basically detect thoughts are the basic bread and buter powers of telepathy all should be able to master. Death urge seems more of a discipline power but its a general.
The kineticist is kinda cool especially with autohypnosis as a class skill but most of the blasting is covered by the basics. Sure the kineticist is better but the basics are covered, this is more like what it should be like.
Also while I think psioncs are liekly balanced I doubt the disciplines are. Shpaers get like 14 powers or so to the telepaths 20, and there are a decent number of really lame powers on the shapers list. Quintessense oh yeah I can preserve really small things.
Some powers seem a bit much, psionic chirgery I think its called allows you to teach others powers if they can manifest that level of powers and it can go beyondthere known power level limit and can include powers form other disciplines. Sure it costs XP, but who wouldn't run around hunting high elvel telepaths down for this kind of hookup almost no matter what the cost.
Overall I got small beefs so far so its a good buy.
