It is kind of a drag that the War Mind uses the same powers, but 'starts over'.
Well, it doesn't actually 'start over', it's substantially better than that. Look at the casting benefits of Psychic Warrior levels:
Power Points: PWs get 0 at level 1, 1 at level 2, 2/level at levels 3-5, 4/level at 6-10, 8/level at 11-15, and 12/level at 16-20. WarMinds, on the other hand, get N+1 at levels 1-5, and N+2 at 6-10, averaging 7/level. So, by level 20, a WM 10 will be only 30pp behind a pure PW (corresponding to 2.5-3 high-end levels of PW).
Powers Known: PWs get 1 new power per level. WMs get one at first level and one at every even level, for a total of 6 powers. However, these aren't as good as additional PW powers, since they're limited in level. If the PW waited until after level 10 to go WM, his highest power would be 4th-level, until he hit WM10 and unlocked one 5th-level power.
The numbers would imply that "+1 level" at 6 or 7 out of the 10 would be balanced (you'd have slightly fewer power points but more powers). The restriction on power levels is harsher, in theory, but in practice it's actually not bad; I converted my pure Psychic Warrior to 3.5E, and one of the problems I had was that there was only one power I even wanted above 4th level (
Form of Doom), until I added some of the Mind's Eye converted powers. As it was, I was picking a bunch of low-level powers in the teens anyway, since I could easily afford to augment them. So, the restriction on spell levels really didn't affect much in my case.
