Knock eats a level 2 slot. I can use that on something offensive. Or Misty Step. Plenty of other important things. I don't long rest every room.
But regardless, it has nothing to do with the scroll thing.
I'm giving you what I believe to be Larian Logic. It's like Bethesda Logic, it just works ™.
They don't want you to feel pressured to bring a caster or cleric or whatever. As it is, not many divine spells are scrolls. Which is fine.
They already have mind read and feather fall, jump and heroism and barkskin and whatnot potions.
Plus what scroll you get tends to be random in loot and vendors.
They've got a reason for what they did.
