The south gets there quicker but the main building on the road has fewer windows and gets rekt from the several buildings across the street. That only leaves the building just south of the VP. Which is quickly destroyed by mortar. Then you have NO garrisons vs the 3 or 4 across the street. Maybe this was meant to be, in some form of asymmetric balance, just like the middle VP building? Left gets the better buildings on the south. Middle gets the northern building. Both are somewhat flankable.
Sometimes when you make a map, you just try to make it look cool and somewhat realistic. There are no symmetric towns in the world right?
Not all maps should be mirrowed.
For example the middle house. Yes you can have a MG there etc. But in latgame you will hate the house when you drive with your tanks
