So, it is not an easy map for newcomers. However, the popular spot, surprisingly, was the sniper platform, with one guy watching the ramp up with the shotgun and 2 to 3 other guys shooting down at zombies from the main lookout. The mansion was also camped quite often but humans were having a hard time surviving in there due to the semi-confined space.
There was also a round (the final round) where I convinced every single human to get together and camp in the basement with the two crates blocking the entryways, and the humans actually managed to survive (barely).
I would say the map has hit that point of good balance. Give me time to test it out with another group though, I want to make sure of my results because I was only able to play it once.
