It would be nice to see a mode that is more faithful to 5e rules. Like disengage being an action, and wizzard's only learning wizard spells. No advantage for height, or being behind someone. Just making it a straight roll plus to hit vs AC. It might make the game a bit slower, and more difficult, but that would be nice. While your at it separating disengage, and jump would be nice. Also consider adding dodge to the actions list.
