Great map, but I noticed a bit of lag online (haven't played SP yet). Wolfgaming's server was a little unstable the last couple of nights, so that could be the problem. My guess is that it would be worse for me (East Coast U.S.) to try it on Hslan or 762 or whatever Euro server is running.
I shouldn't, in theory, lag: Phenom II 1055T CPU, 4 GB DDR3 1600 RAM, and ATI 5670 Radeon GPU.
Overall, the map plays really well. I've been on two German teams now, both of which won the map. I've yet to see the Amis use the mortars, which might help their cause.
I have a feeling a large amount of playtesting went on to balance the map. I'm curious as to why the German's kits are mostly limited. I'm not complaining (it adds a good wrinkle, IMHO), but interested in how the betatesters came up with that suggestion.
