I was surprised to see that everyone could use every scroll initially, then I felt that it made sense given how DOS2 worked, and that this is a mainstream AAA title. The example of the fighter having access to gold and being able to out-wizard a wizard gives me pause.
Scrolls for classes that don't include your class (or subclass in the case of EK and AT) should not be useable as a core rule. I would not be opposed to this being optional in easy mode games, but this unbalances the game tremendously to favor fighters specifically, and probably rogues a bit too, with their two bonus actions a turn.
I would encourage Larian not to be afraid of forcing players to make thoughtful decisions about their party, but I don't have any hopes that they will. It's normal for every game developer, both pen and paper and video game, to remove all consequence from player decisions and allow them to do anything. I would be happy to see a player punished for failing to have a healer among his party, or enough gold to pay an NPC for an expensive raise dead spell.
Either way though. A Core rules mode shouldn't feature universal magic item usage.
