The thing BAP does for an LRM boat, is if a Raven with ECM wanders by, and it decides to stay near you (without even attacking), it can't lock you down.
That's a big deal. Sometimes I'd end up near some kind of light vs. light battle, and without them even worrying about me, shut down my LRM's.
And even in a 98kph Centurion, you can't exactly outrun them. So for something like a Stalker with LRM's, they are effectively shutting down those weapons, with no real skill required.
If you have enemy mech that close, especially if you are a long range support, you have other things to worry about then trying to lock onto a target that 500+meters away.
