Tested your map last night. It seemed to play well and after the first couple rounds it seemed everyone knew what they were supposed to be doing.
One thing that was kind of odd was that you could get on the walls on the side and back of the base, but you couldn't get on top of the base. It is really odd to not have anything over your head and looking at someone who is on the wall behind your base, but not be able to get up there without leaving the base and going around.
By the fourth round people realized you could just stand in your own base and shoot the computers all the way accross the map. It that that there should be a little more cover in the middle to make it so that the other team has to stand outside their base to have a clear shot down the middle.
Once you have a couple soldiers and heavys shooting at the center of your base across the map there really isn't a whole lot you can do to protect it and it turns into a match of who can rocket spam the fastest. Splitting up the computers would help this. If you spread them out along the back wall the other team would have to break more of the base in order ot have a clear shot accross the map.
All in all I liked the map and it got pretty decent ratings. Once you finish detailing everything you should be in pretty good shape.
