The whole idea of dumb firing "leading" LRM fire in ludicrous. for the following reasons:
-Unlike LOS weapons, missles do not travel in a straight line. They travel in an arc, and impact on a specific location based on the distance where the reticle is targeted at that time. You would have to determine the distance the mech is at, then try and predict movement, then try to target a landscape feature in the probable location at the correct distance.
-LRM travel speed is 100 m per second. At 500 m, it would take 5 seconds for the missiles traveling to that point, more than sufficient time for even an Atlas to move well past the impact point. For comparison, look at projectile speeds:
* AC2 2000 m/s
* AC/20 projectile set to 900m/s (750m/s previous)
* AC/10 projectile set to 1100m/s (850m/s previous)
* UAC/5 projectile set to 1300m/s (900m/s previous)
* AC/5 projectile set to 1300m/s (900m/s previous)
* LBX/10 projectile set to 1100m/s (850m/s previous)
...and PPCs:
* PPC projectile speed increased to 2000m/s
* ERPPC projectile speed matched to regular PPC (2000m/s)
And continue in a straight line, so if the target is retreating, the projectile can still "catch" the target. The slowest projectile is
9 TIMES FASTER than LRMs!
This is also why TAG is ineffective. A target at 700 m, you have to keep that TAG pinpointed on that target for approximately 10-12 seconds, 1-2 seconds for people to react to the target TAG, 1-2 seconds to actually click the button and the firing delay, and 7 seconds minimum for travel time. Try to keep that TAG on a Commando running in and out of landscape features for that amount of time, you'll find it harder than you think. So even with TAG, LRMs are really only effective at a few hundred meters with the current ECM mechanics, mostly due to travel time.
So please, just stop trying to sell that line, that dog will not hunt.
