I have been intrigued by Rowling's statement that the four houses
represent the four elements.  In astrology, each of the three signs
associated with a particular element has its negative and positive
expression, but no sign is superior to any other.

Rowling has shown us good and bad Gryffindors, and bad Slytherins. 
She has implied that there are good Slytherins and she has also
implied that no house is superior to any other.

So what would a "bad" Hufflepuff trait be if not conformity? (I should
have used the word "conformity" rather than "mediocrity".  It is
closer to what I was trying to say.)

What is a "bad" Ravenclaw like?  We know the virtues of the other two
houses.  What are their vices?

I am open to suggestions.
