Example:
AT-RT with Flamethrower wants to shoot at some dues on the top of a building. The AT-RT is on the ground below the building. He has LOS to the dudes.
If we lay the 1-Range ruler flat on the ground, the defending stormtroopers are within Range 1.
If we angle the Range ruler so it makes a straight line between the base of the AT-RT and the Stormtroopers on the roof, it comes up short.
I don't have a pic of the exact situation, but here is pic from the match where it happened.
The AT-RT was on the ground between the statue and the building, and the troopers were on the top of the building.
We played that it should be point to point for range, since that just made the most sense thematically. But this game's rules don't always follow what makes most sense to me thematically.
