I wasn't able to pug your map, but I went over it with some people and these are some things we thought you might want to change. Most of these screens are from a6, but the criticism still generally applies to a7. Oh, there's like no order to these and I'm not really going to try and make one since it's pretty late.
These crates are like the bane of my existence, they look like you should be able to jump on them, but try all you want, you usually can't do it. Can you sink one into the ground a little, or raise the ground a bit so that you can jump onto it and then access that upper area as a medic?
The entrances to last are way too close together, it's way too easy to watch both and most likely control them completely.
Can you add some crate or something to middle to allow a non triple jumping scout to get on top of these metal sheets?
These sightlines on mid are really ridiculous. For the second one, you could just make that a hallway and completely remove it, for the third, you could put some metal sheets on the front of the roof to obstruct the view. Idk anything easy you could do for the first. You'd probably have to rearrange mid quite a bit to get rid of it. The first two spots also let you rotate between each place really easily too, so it'd be pretty hard to spam a sniper there. There's also too much ammo and health by both these places, would make camping way too effective.
This spot would make a roamer a nightmare on last. He could sit up there and rotate quickly to either door based on what his team calls and just destroy anything that isn't ubered.
I liked a6's last a lot more than that of a7, it's much more interesting. I think you should make the sort of house over the point similar to Gravelpit B in that there's a hole in the roof that you could spam the point thru. That would allow for a dynamic fight for roof control when pushing last, I think it would make for pretty interesting game play, maybe.
This hallway behind 2 is really useless, I would either get rid of it or throw a pill in here or something.
I don't like 2, it's really boring and has sightlines that seem really abusable. I think you might want to raise the point to the level that the satellite dish is at now and raise the satellite dish and the surrounding buildings accordingly to accommodate such a change. Raising the point would give the defenders a bit more fair ground since, the way it is now, the attackers can go upper left and automatically have height on the defense, if the point were raised, at least both teams would be eye to eye, so to speak. Height also has the benefit of just being interesting, both in the sense of visuals and gameplay, or at least I think so, anyway.
Scorpio thought that this fence should probably be solid since you get a lot of information while standing behind it without having to risk much. I also don't really like fences like this because at a distance, it can sometimes be difficult to tell whether a players is behind it or in front of it, or if the fence is even there, for that mattter.
We thought you should add a ramp or some boxes you could jump up where the blast mark is in this picture, since, if you're a medic and you fall in the pit, you're kind of screwed since it takes so long to get out again. Another way back to the point would also just be nice since, the way it is, it seems like that lower area would just be a death trap and having multiple ways to take to get out would probably aide players' survivability.
People also felt the distance from spawn to the last point was much to large. Idk if you have spawn times set up to counter that or not, though.
