Two Sets of Rules, the Good and Bad?

[OldTrees1]

There is no controversy over whether "whether the DM should have to use the PHB rules". Literally nobody on this thread is arguing that position, ergo there's no controversy.

There are people though who seem to be arguing that a DM should never use PHB rules for NPCs, and others who disagree. Ergo, controversy.

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"

Even the OP is asking about degrees (asking the good and the bad over having different rules)

You can if you want to, just like you can stand up and turn around three times before you roll your dice.

What, you mean you don't do the hokey pokey before each roll?
