huh? two mechs with 1 AMS each can shoot down most missiles from a clan lrm boat.
clan missiles are super easy to shoot down because of their ripple fire.
This second statement is actually not true (in the case of a Clan missile boat)
AMS gets easily overwhelmed regardless, and as a person who frequently uses twin AMS on my IS mechs I can tell you that LRMs from the Clans actually can fire at such an overwhelming pace that the AMS actually stops destroying missiles at any reasonable rate... as a result of the ripple fire.
This is because missiles each have individual health pools of 1 to 3 HP. A single AMS delivers 1.5 damage per second (or +0.75 for each overload node taken up to a maximum of 3 damage per second). Yes, this means twin AMS could churn out 6 damage per second, taking out 6 LRMs or 3 SRMs each second.
Where this falls apart is AMS automatically targets the closest missile within a certain minimum range. Unfortunately this minimum range isn't far enough to afford a full half second of fire, and takes a quarter of a second to change targets, meaning it literally has 0.25 seconds to destroy a target. Consider also that the server runs at 100 frames per second, which is also why damage registration issues occur whenever the server FPS drops or the missiles start hitting in a hundredth of a frame.
As such, you enter a state where the twin AMS are trying to target identical missiles, with less than 0.25 seconds to destroy it, and regardless of success or failure it has just that long to select a new missile that, in that amount of time, has already hit you, then it needs to choose another, but that hit you, then it chooses another, but that hit you, and in effect it enters a state where it is destroying less than 1 missile every 3 seconds despite having 6 damage per second. Then the IS mech is destroyed.
IS missiles on the other hand, yes they hit all at once and in small amounts are harder to destroy, but in large volumes Clan AMS, even with just 2, has a better chance of destroying at least some of them per volley because it cannot be as overwhelmed except in the case of old LRM-5s. Even then, well you can destroy 6 missiles in a second.So the case that Clan LRMs (From an LRM boat) are easily destroyed is actually a fallacy. From a boat, they are virtually invincible.
I stated Clan AMS against IS LRMs, but in truth this is true of all AMS. AMS has a better chance against IS LRM boats than Clan LRM boats due to the fact that in volley fire, there isn't enough frequency to individual missiles to overwhelm the AMS's, uh, "AI" or should I just say the mechanics of how it works? Either way ripple fire overwhelms AMS. The same is true for MRMs against AMS, because the ripple fire stream of enough missiles basically makes AMS completely ineffectual, since AMS "ticks" down the health of a specific missile until it reaches 0 or it hits, then spends 1/4th of a second picking a new missile within a minimum range and starts again. This is actually why almost no MRMs end up destroyed. And potentially why MRMs have terrible damage registration (they fire in their stream so quickly that they hit in between each 100th of a second, thus their explosions don't exist client side.)
From a single launcher or two fired at the same time, or any amount fired at the same time, "Clan" LRMs are 'worthless'
Fired in tandem from a boat carrying 4 to 6 or more launchers, they are nearly impossible to shoot down with just 2 AMS.
IS LRMs fired from a single launcher or two at the same time they are very effective against AMS when compared to the same for Clan LRMs.
IS LRMs fired in tandem still lose roughly the same number of missiles per volley. Where Clan LRMs significantly reduce how many missiles they lose.
There is an edge case if you're firing on a farther target that has one AMS and another mech allied to that has its own AMS, but this is because the overwhelming effect is not occurring to at least one AMS.
TL;DR:
When it comes to boated LRMs, IS LRMs are easily shot down against even odds of AMS (2 AMS of either IS or Clan origin on a single mech) while Clan LRMs become invincible after several seconds of sustained fire.
