I think reverting the lynchpins back to optical would better if you just made them have less range, with less maneuverability so you cant fire behind mountains, and less damage. And remove them from compass.
You still have 42 rockets which seems great if you dont care about time in danger zone, where you will die to an airplane or sarh waiting for each tracked target to be destroyed while in multiplayer. AGMs were buffed with terrain avoidance, which should have made them special compared to lynchpins, even without nerfs. For apcs and tracked vehicles, they could have been made more resistant to them. I see the main complaint was that killing ships and AA was too easy. Is there someone that doesnt know launching 4 agm68s at any distance is more lethal and safe than using lynchpins? Removing lynchpin loadout from compass would do half the work in this area. They are of zero value against anything bigger than a shard, and the fun from seeing them hit all parts of the ship like artillery is never gonna be felt again, because they target the belt of ships. They wont even center on the command bridge. The only weapons that can target ship defences now are ones that will cripple the ship anyway. If im in a chicane within 7km of your ship I deserve to cripple it if i can do it easier in a compass already. And why should i not get rewarded for flying my chicane stealthy all the way to an enemy base? Surprise assaults in a chicane are the worst of surprise attackers now, because a player can die, respawn, then kill you with guided munitions before you can use half of your loadout. Thats the reward for getting within 7km of enemy base with a heli. Even if you dont care about balance, using dozens of rockets to saturate areas was cool and fun.
TLDR; any nerf EXCEPT it being laser guided would have been more fun
