Hello to Devs .... and thank you for a great game!
(1) The cav units do NOT need to spawn SO FAR from the main body. They seem to be placed as though there is always lots of room. Simply have them spawn initially close in to the main body of the army. It is easy enough for the player to direct them after that.
(2) After no.1 above, examine the spawn points on all maps. It will not be all that noticeable on the map if some rock outcroppings and/or cliffs are eliminated. What's important is that the army doesn't have to look like it is defying gravity by spawning on a 45 degree incline.
It is only what is directly in front that is important (and the maps are great!)
What Olympeus mentioned above is what totally breaks 'immersiveness' in games. This one, however, is easy to fix.
Thank you !
