My idea RAC:

But since I doubt it will work like that on top of the other mentioned reasons earlier I have now switch gears and am looking forward to the ATMs and MRMs. With some of the medium and light Inner Sphere mechs that have a few missile hard points the large volume MRMs will help them out, (example: 40 MRM).
For the clan an ATM of 3, 6, 9, or 12 and then boat them ... so my Jenner IIC loaded with 6 ATM 3s? Why not, and slap that clap or lap in or both maybe to help negate the ECM. Considering the ATMs should do more damage at close range makes this great for light hunting and stil usable when the enemy gets out past the distance a streak would go.
Them for bigger mechs and those who want to lrm boat now can have a few big packs of ATMs for anti light mech. Example of that would be 2 ATM 12s with a tone of ammo or two.
