Nos1001 is right, use a hypotenuse.

Yes, he can douche his way out of getting assaulted.

This works especially well against big based models like WraithKnights, DreadKnights, Mawlocs, etc.
Fluff-wise, I like it, makes sense.. If the guy is standing at the wall's edge while you run up from the ground ....
Smaller infantry prolly *can* go under the ruins, and then up, but this could open up, "Hey, man, that's not the shortest route" counter argument. I'm more of a 'do what's sportsmanly and fun' kind of player.

I would disagree. Terrain is decently defined in this edition. Page 37 will be your source on the
MC 'toe in' question. For vehicles, page 77, second bullet.

Page 108 is a good read, too.
