From testing it, I would suggest moving the spawn room into the center, to encourage people to use both the right and the left exits. At the moment, 90% of people go left because it's right there. But the right route (which leads to the sniper deck) is hardly ever used, which means I was finding a lot of opposing team members (mostly heavies) just camping the right buildings and our sniper deck.
It used to be in the center but people said move it to the side so its the same distance as the other side.
