my point it that there isn't an actual height to play with at any point a unit can only be on 2 heights: ground or air (or lifting off/touching down but those are transition animations)
that the map has levels is a hack with sight and path blockers and unimportant to playing, cliffs act as a path blocker and a 1 way sight blocker while ramps just act as a 1 way sight blocker. air units ignore both either way.
