I disagree with their assertion that a 10th level character should have an easier time avoiding the ghoul's effect than a 5th level. They should have an easier time dispatching a ghoul, as reflected by hit points, but a large group of ghouls should be terrifying to even a high level party precisely due to their paralyzing effects.
That doesn't sound right to me. As a 10th level fighter, I don't want to be terrified by a handful of 2nd or 3rd level monsters. (Facing 20 ghouls by myself, sure that's scary, but two or three shouldn't be a concern.)
Plus, it messes up the encounter building math. It's hard to calculate the difficulty of encounters when some times of lower level monsters (e.g. ghouls) stay dangerous longer than other comparable lower level monsters (e.g. bugbears).
