I really wanted to see a Core Rules difficulty setting. With stuff like...

- Scrolls restricted to spellcasting classes
- Prepared casters actually having to make choices memorizing instead of just changing their spells at-will and effectively having everything available at all times
- Shove being an Attack Action with the distance buff removed
- Actual restrictions or consequences for spamming Long Rest
- Multiclassing stat requirements enforced
- No potion throwing
etc...

But instead we get Tactician where there are more explosive barrels and arrows. Not exactly the same thing. Quite the opposite in fact.
