It's very easy to miss shots in that game. My fault for getting too used to the Source engine and its hitscans.
The map may need a bit of balancing work. The first objective is about the only strong defensive point, and the middle objectives are fairly easy to push through once the first one is done. The vast majority of the defender victories I've encountered occur at the first defensive point, and maybe once or twice the attackers are stopped at the final point.
Oh, and you can stay alive forever in the Bravo ditch at the first objective. If you're new to this game, I highly recommend being a medic in that ditch.
