This map was "interesting".
Oh, Blu spawned ontop of each other so there doesn't seem to be enough spawn points placed.
The first point was easy to cap whilst the second is rather difficult (due to being directly before the defenders advanced spawn). The fact our team (in the second match) managed to cap it was shere luck on my part, having remained after a mutual team wipe, and my whole team spawning ahead of the cart and moving onto the next area which was completely undefended.
Move the spawn away from the tracks, i would recommend changing the doors to the other side of the room/building.
Also, in the first area, Blu can be sniped in their spawn. they have to expose themselves when exiting the room they spawn in before leaving their spawn area. It wasn't an issue in the game we had, but i did notice that this was a possibility and may occur in future if not resolved.
I can't say much for the third cap, we pretty much steam rolled that which was a result of: RED being over extended, which then switched to BLU being over extended when they went for the final cap.
It takes ~18 seconds to get to the staging point
using the shortcut from the advanced spawn, which was luckily not sentry/demo camped (mostly due to the steamroll on the cap point before). The second one way door was however frequently camped by scouts and demo's. The tiny door size also lends itself to sniper camping directly from the RED spawn exit. It needs more cover.
As you can see in the following image:
All those catwalks and platforms on the left. Get rid of them. They are a nuisance to traverse and funnel BLU's flanking attack right out in the open. Replace it with a raised platform of some sort.
Shorten the final cap area as illustrated, you actually have to pass RED's spawn to cap (which is bad), although we had the cart right on the edge, we were getting slaughtered by sentry nests outside RED's own spawn, looking back on the point from behind. Usually at this point it only takes one or two strey players to nudge it in, but this was impossible due to RED camped directly outside their own spawn area, killing us before we could touch the cart.
