2. To hit advantage for player (like X-COM)
3. To hit advantage for player and to miss disadvantage (like X-COM)

The same could be an option for surfaces (damage rules), cantrip (surface&damage rules), and much else.

The trouble with adding a multitude of gameplay-affecting options is that it makes the gameplay harder to balance and test, which increases the workload of the QA team tremendously.
