I like this rule for hex play. Its a simple enough change and makes total sense. I always hated how 2 mechs offset by 1 on a hexline cant be strafed as it must be 5 hexes in a straight line. This rule works perfectly well... any 2 models within 5 hexes of each other can be strafed now that the line can be drawn anywhere. It makes strafe go from the worst option that I never use to one I might use.
