To Bereth, here is a video of me doing the demo rollout with buff from the medic:

You arrive at mid with ~90 health, and the small pack at mid will get you up to ~120 health. Because the demo rollout at this speed is around 3-5 seconds faster than the other rollouts, you shouldn't need more. If you want more at the cost of speed, you can get back to full health by picking up the medium pack by going left into crane room and then back out.
Brrton (as well as everyone) thanks for feedback so quickly. I do have the addition of a second spawn door on my list of changes to be made, although I haven't done so. I didn't add a second spawn door for a10 because I realized that to push onto last you really need at least 2 picks; and given the capture time on last (it's similar to badlands at the moment) spawncamping doesn't seem like much of an issue. It is planned to put another door in.
As far as capping 2nd coming from last, it's already decently difficult. Because of the balcony, the team defending second from yard/mid side has a decent advantage. What I've seen in PUGs is that it's typically easier to push 2nd-last than last-2nd, interestingly enough. Of course, we haven't had legitimate teams play on the map yet so I'm definitely still willing to revise that statement, but at the moment I'm not sure it's too much of an issue.
The ceiling height issue, the doors being a little small, that stuff can be fixed easy. Added to the changelist.
I haven't considered kritz through that opening. It was put there originally for the demo rollout. That would be interesting, I've not seen that used. Kritz in general is pretty good on this map. I was considering putting a door or hatch on that window, so that it's open when you own 2nd but closed otherwise.
That flank used to be a bit more sneaky, with the opening not visible and it made it too easy to get into 2nd. It's still there, but it can be removed. I haven't really seen a reason to get rid of it, but at the same time it is kinda useless.
Mid seems to fluctuate between too big and too open vs. too closed and too small between versions. It did get a decent amount smaller, widthwise, since the beginning, and I have thought about shrinking it a bit lengthwise but I'm still not sure if I want to or not (part of the reason why I posted the map here!).
Also, your positioning for second is really interesting. I will definitely try it in a future version and see if it plays better. I'm not quite sure what I would do with the current 2nd building, though.
Once again, thanks for all of the quick feedback guys!
