Having read both books and playing the CRPG I'd have to say the monsters are spot on. What people are missing is that the game is set up just like the CRPG in that characters from 1-5 could face any of those monsters in their adventure. I agree some balance would be nice, such as suggested number of each for a given encounter situation, but their inclusion in the 1-5 book is suppose to fill that purpose. Just as in the CRPG the game really stresses tactics versus just running in half cocked and expecting to overwhelm whatever you see there.
