Lie is used very loosely thes days. As is truth.That is what a revision does... it revises things to improve them. WotC has been very clear that this is revised 5e.
Some people seem to want to use the rules as a stick rather than a guidepost.Fun fact. In a different thread a poster hates that the 2014 DMG states in every single optional rule that you can use it or not. Your choice. It is your game.
I thought it can't be stated often enough.
Probably a DMG that only repeats this for 300 pages is more useful than the rest of the 2014 DMG.
