The lock of the LRMs in MW must be the same as with a firing solution for a torpedo of a submarine...that meens with the actual direction and speed of the target you will hit it. When the salvo is in the air and the target doge you may miss.
Considering this point of view...what about achieving target lock in every position of you reticle - if you hit is no depending on the position of your torso, too. If the target stood still and you didn't move, using a low angle the lock is achived in split seconds.
Is the target moving with 100kph and you are running behind you maybe need some seconds to get lock....and so on
To make them active lock and mobile enough to hit a target may be the easier way to implement.
