The game is rather easy right now due to unlimited resting. You don't really need consumables because you can always engage at 100% for free. You build up tons of economic/loot momentum and the game snowballs from there.
That's why I'm really hoping the game difficulty will be more than just monsters having bloated stats. I'd prefer a system where you can increase the macro difficulty too - i.e. resting options/requirements, # of short rest, etc.
But if they are going to implement that, Larian will need to improve their difficulty settings from DOS 2, since people will have varying taste. Hopefully they'll need more customization options (instead of just story classic, tactician) - maybe something like Kingmaker with various option sliders.
