Hey Tortuous, not to detract from NARC, which is still useful to Artemis for giving you consistent locks even when your foes break line of sight, but unfortunately the NARC tracking bonus is denied to Artemis Equipped LRMS as regards tracking and lock speed. The additive aspects of the aiming tech available is such that ARTEMIS+TAG stack and TAG+NARC stack, but on an ARTEMIS system the ARTEMIS tracking bonus is either there or it is not - so when you actually lose line of sight and thus the ARTEMIS tracking bonus, NARCs tracking bonus does not kick in just because the Artemis bonus is gone - though the TAG bonus should still be there like if the TAG is being done by someone at a different angle, still successfully. It's been gone over a lot on these forums and in DEV posts and the few times I've cornered actual devs in live chats, or games they've confirmed this.
It's been supported by private lobby testing as well, where our Artemis LRMS really should have been doing work on a test NARCed player in the (red) team, but the broken line of sight on the ARTEMIS was enough that tracking really visibly deteriorated, where before missiles actually correcting trajectory and making tight turns after passing over a wall, when a little bit of the NARCed mech was showing (thus Artemis was active), as soon as the mech fully was backed out of site (and thus it was now NARC+TAG lock only) the missiles could not do this tight turn and would hit the top edge of the wall or at an angle behind the mech who was NARCed and pressed tight to the cover. I would believe that if NARC was still giving it's 50% better tracking/lock time at this point when working WITH TAG, those missiles would still have corrected after passing over the cover and in fact, when later testing in the same location using a missile mech mounting only LRM 15, rather than LRM15+Artemis, the tracking seemed intact and better on the NARCed mech, properly making an angle over the cover and correcting last minute to catch this NARCed target with missiles. While some finesse may have been involved on the firing missile boat, in having the narc lock, firing the missiles, breaking lock so they took a high arc, then restoring lock so they dived on the mech - I really think from what we saw, that it supported this assertion about Narc not playing well with Artemis - as stated in past DEV posts still searchable on the forums.
Ah, thank you very much for this, I had long heard about it but couldn't get absolute confirmation as a solo player, and the search function on this forum is awful enough that I didn't find an answer.
But I am actually glad you brought this up, because the most interesting thing I've observed about running a NARC on an LRM mech, is that the locking and tracking buffs make up maybe about 5% of the system's usefulness. The locking bonus is mostly pointless, since you'll probably get a full lock when NARCing your target, and even if you move somewhere else, no return fire means that there's no pressure requiring a faster lock. The tracking bonus has a usefulness that's relative to the mobility of the target; the faster the mech, the more you need it to land your damage. However, the NARC is more effective the slower the target is, because the missile is not only easier to land, but it takes the target longer to reach cover as well.
So even knowing that having Artemis negates the locking and tracking buffs of my NARC, I'm still hesitant to take either off, as they both seem to serve unique purposes. Artemis+Tag reduces my missile spread, allows me to counter light ECM with line of sight, and grants me strong buffs to locking and tracking targets in line of sight. NARC allows me to turn off heavier mech's ECM for 30+ seconds, move to an optimal position that does not have line of sight, and chainfire LRM15's onto my opponent risk free until they die or run to cover.
They're very different tools that let you do very different things, I think taking advantage of what all of them give you, while not sacrificing a solid secondary weapon system, brings out some of the real potential of LRMs.
