Not as bad sounding as you might think. Ran around the map a bit, seems pretty interesting. At the very least it makes for a fast paced/non-stalematey map. You basically have the equivalent of one point to push through, and then all you gotta do is land a player on the pit.
So my comments from what I saw running around the map:
On the + side, engi won't be as effective because there's so much back and forth.
On the -, Sniper will be mandatory on both sides. I think the yard area could use a lot of work, feels very bare and that's an enormous sightline.
I feel like the area between yard can pit is largely useless. Once the defending team loses yard they're going to pull all the way back so they can watch every entrance to the pit. Besides, that area is like well 2nd point complicated.
Last thing is there's a lot of prop usage, and little bits of terrain that would make it extremely annoying for soldiers to shoot or players to navigate, like the edges on the outside of the windows or the bleachers and tables in yard.
I like the idea though, would be really interesting to try playing on.
