Sad to hear that.

Anyway, I had a realy great game yesterday, one of the best during the last weeks.
Tha maps a such is well designed and with a great variety. On the one hand, there is a big city in the middle for infantry-fighting, but you also have the wide, open terrains for the tanks with some villages and stuff to fight for. So, the overall design is unique in the PR-world and thats what makes it outstanding.
Maybe you could add some further stuff, like a bunker area, of an old, abandoned Outpost or what ever, so that the open terrain does not look that empty.
So, good job on this one.
Anyway, two points i want to mention:
All in all my FPS were good and I had no lags. (everything on high, win7, core i7, 6GB Ram, nvidia gtx275) but in the city there was one awful drop in fraps. In the City, there is this one big construction-site and when i was aiming at the northwest building while I was in the building south of it, my FPS droped and it was almost unplayabley laggy. Sry that I don't have any pics, but we were in some hard firefight there so there was no time to start XFire etc.
If you need any further info on that, I will try to get you some screens of that area.
The second thing is the flag-layout in the city. Yesterday, in the second round, there were two flags right in the city. Since both teams were almost equally balanced, we were fighting only in the city for most of the round, which gets a bit boring soon, when you have a huge area around, where you could be fighting if the flags were not only in the city.
So, if you are planning to use AAS4, maybe do not put two flags in the city, because this only drwas the attention to the city and you will hardly get the oportunity to play on the whole map.
I hope I can help a bit with my feedback, to make this map as great as it should be.
Oh, btw: I really apreciate such a public beta-test. Not just, because I'm always curious on the new maps, but because it really helps to make map a huge succes once its fully released. Especially on the large 4km maps, it's hard for a "normal" betatesting team to test the whole map. So, in my eyes every new PR-map shuld be tested like this, to avoid them needing a second realease until they are balanced and fun to play.
Just my 2 cents, so...
