First thing, please add lights! It's not too hard to do, and it increases the quality of your map considerably.
It looks like Red has lots of height advantage at A, but not very much at B, which suggests tat it might be slightly harder to cap A than it would be B.
The journey from A to B also looks a bit corridory and spammy, although i'm only seeing that from the topdown view.
When you get Alpha 1 uploaded, i'll want to check it out and look around
