"Block cliffs" (those that serve only to block path and LOS) are higher, and those that are near the natural became too high, so I had to put some rocks to make units visible all the time. (Even so, I don't think I acomplished what I desired.)

I don't know how to make cliffs unclimbable at the same time that they are "low" cliffs... Any help here is very welcome.

Not simetrical, thus it is not balanced. The distance from the high yeld minerals are not the same (I think), and the area of construction of the main base may not be similar.
