Really nice builds!! You gave me some ideas to make nice encounters!! Only thing I disagree with you is the HP those builds have. I prefer to stay in the margins of the 50% (soldiers have 5/6 more HP for each level, for example) so they can really punch enemies but die easy. I would say that the CL4 is not real as they are, in reality, very optimized. CL5 is my valoration.
With these two things, typical NPC would have 28HP (2+3+2+3+2+3+2+3 +8*CON) for the three first CLs levels and 13 for the last two, 41 for a CL5 character is above non combat heroic classes with a really high BaB.
