Yes, but follow up intercepts for leakers is rather important. Assuming interception rates are roughly the same as in TN Aurora, you're going to want many interception chances.
In fact, given that missiles tend towards one-hit-one-kill, AMM defense is pretty much compulsory. Beam only defense gets one shot on the final approach, and a full salvo of ASMs will very likely leak at least one. (remember that ASMs can do evasive maneuvers too, and they have a tiny cross-section to displace)
