Horde AI overhaul needed

[S0M3D1CK]

The one thing that bothers me abount base building in 7 DTD is having to build a base with the same assumptions based on the AI spawning. I wish consideration could some how be taken for topography. Its annoying to build on flat land assuming a 360 degree spawn radius. It would be fun to build in valleys and mountains but you really can't.  I kind wish spawns could be limited on certain terrains so you can build more real world style fortifications and not have to worry so much about zombies falling on you due to a technical limitation.
