The F-14A is an unusual outlier here; it is the only 12.7 aircraft without access to an all-aspect air-to-air missile. Adding AIM-9Ls to it is really a nothingburger within the already compressed 12.3-13.3 BR range.
People typically run a loadout of six AIM-54As and two AIM-9Hs. Replacing those two AIM-9Hs with AIM-9Ls surely must be the earth-shattering balance change, right?
While I recognize that this BR range suffers from serious compression issues, decompression is a broader systemic change that is very unlikely to be addressed through a dev server. That discussion should belong in the BR change feedback.
