I just wanted to lay down a thought on the NPC Peasant class, of all things. Basically, my issue is with the warrior's moderate archetype power. 4 HP per hit die seems a little high. Assuming max health per level, this puts them on par with hunters. That may not be too bad. However, many DMs seem to like running average health per level. By the way the system works, this would mean that a warrior peasant gains HP each level equal to a sentinel.

Health Progression (Warrior)
4 + 2 + 3 + 2 + 3 + 2 + (4*6) = 40
Health Progression (Sentinel)
12 + 6 + 7 + 6 + 7 + 6 = 44
Health Progression (Gladiator)
10 + 5 + 6 + 5 + 6 + 5 = 37

Of course, all of this ignores constitution modifiers. I'll assume that many combat PCs will have a higher Cont score than an NPC. Still, I just wanted to bring this up.
