BLU won each round. A and B were too hard to defend, and after a time BLU also capped C when they finally got to the mass of cover with the containers and stuff.
I think A and B are too close to eachother and also a little too close to the spawn. Move them back a little, that way the area for C will also shrink down a bit. You might also want to try to make it not that easy to change from A to B. When you play gravelpit you will see that you have to chose to go to A or B immediately when you live spawn. And if you leave spawn, A and B aren't immediately behind the doors already. When you have chosen a point in gravelpit it will also take long to get to the other one, in your map the distance between A and B isn't that long.
Also, fix the damn sniperlines please, there was Okrag sniping from C to our spawn when that door at A or B opened. And getting to C by using that route was always very difficult because of the camping snipers over there.
