Two Sets of Rules, the Good and Bad?

[MaxWilson]

I have not seen either extreme in this thread. I have seen people describe a preference and appreciation for there being simpler rules. I have seen people describe how they did not like the more complicated rules.

However I have not seen the "The PHB rules must/must not be used"

NorthernPhoenix and PhoenixPhyre both seem to hold this position, that DMs should never use PHB rules for NPCs. (99.999999% says PhoenixPhyre, but unless she gives an example this seems like an assertion of "never.")
