Only "nerfing" the things will mean people won't use them much

Not really. There is no alternative to PDC besides taking the hit and dying.
Reducing the accuracy could improve the statistics for missiles.

In addition, if we went back to the unlimited range missiles from SE3, it could help too... no more missile dancing. With mounts we can keep the launch ranges the same as unmodded, so there won't be any difference for the AIs.

There's little reason to use these, compared to APBs. Give them a range advantage (say, 50% more range than comparable-level APBs) while decreasing their damage slightly (say, 80% as much as an APB's max-range hit) and that may change; the choice owudl be close-range high-damage, or, long-range low(ish)-damage.

What about leaving the same range as APB, but with APB decreasing over distance, and MB doing the same damage everywhere as the APB does at its mid-point?
