Just got my copy.
It's really odd to me how the various PC analogs are scattered around and their power levels.
The Wizards are great organizationally being all together, but why do the different schools range from 8d8 hp, DC 13, CR 3 to 22d8 hp, DC 15, CR 9)?
For the others, why are some by class name (Bard) and others not (Archer, Archdruid, Champion, Martial Arts Adept, and Master Thief?). Some of it annoyed me in the back of the MM, but having to look for them all over might be great for running a module, but is the worst for building one.
My kingdom (or at least $49.99) for a Tome of NPCs giving a sample of them at different levels arranged by class.
