I also think they need to think further on the rest system in general, I'm seeing that it has very little to no consequences, which I expect it should, considering there's a mind flayer tadpole eating away at your brain.
Even if it isn't changing you because of Netherese meddling, more urgency in your mission, changes that happen to character attitudes.
Too much urgency doesn't work, because we're given so many side quests in just Act 1 to complete. So the game gives us a very early conversation in camp that explains we are not following the normal infection schedule with the tadpole.
There are also hints that we're being groomed for a higher purpose involving the tadpole, and not just the usual transformation. Which is another way of shutting down the timer.
