I mean... if you can take a long rest whenever you want, and with the clock, you can, there's no reason to ever pick a warlock over a wizard.
There is in my games and in yours because we'll always try to avoid the "wait" button or try not to use mini games to earn "resting points".
Why should I care if there's no reasons in someone else's playthrough ?
The game is telling me when it's dark. But if it's not, I can always "click a button" to wait until it is.
It's not at all the same.
In your system or with a clock defining when you can rest, the game gives you a challenge (you can eventually bypass)
At the moment it doesn't at all. Which is sad because that's exactly why the resting system and the spellslots management are interresting for.
