- Yes. Per RaW there is line of sight.
- Yes, you did here of something else. Yes it was me.
This is the rule I created:
8.3.4 Presumed Crest Lines
The LOS between units of different elevations is blocked if the higher unit is behind the crest of the hill. If the highest unit has a higher elevation line behind it, which is also on the same hill, the units are in LOS of each other.
Not a perfect solution, but quite workable.
Keep in mind, if you are teaching someone the game, stay RaW.
