IS LRM's
do not do any damage under 180m
Clan LRM's
Will do damage under 180m, but in reality, if you are using them under about 140-150, they aren't doing anywhere near enough to be worth the ammo or heat. the amount of damage is on a curve, So 180 full, 150, i think is something like half, 120, its barely 1/4 if memory serves me correct. Maybe some kind soul has a linky to the chart.. I forget where i saw it, but i do know it was a rapid drop off down to nothing. Pretty much you would only fire them say under 140-150 if either you had no other weapons, or the target is basically dead anyway.
General Lock info
As far as locks go, they are completely unreliable most of the time, unless someone gets into a brawl out in the open, but at that point you can most likely grab the lock yourself.
Personally i run my LRM mechs light on ammo, and i pretty much only fire if i have my own lock. I only blind fire if something is narc'd, or i know it's out in the open in a brawl. Though if i am on a decent team and notice one person holding locks very well i might, but by that point i am most likely in LOS anyway to help share armor and distract.
Locks take a few seconds to grab, Adding Artemis, BAP, TAG, NARC will all speed up your lock acquire time.
TAG
If you are running an LRM mech, do yourself a favor and try to load up Tag every time, even if you just have a single 15 launcher. it's worth it. It can also counter ECM at range which is totally sweet. ECM guy gets out in the open, Tag um, and lock up and watch your team light um up with direct fire weapons.
BAP
For LRM use, i pretty much only use it on mechs i know that can spare the weight, OR if it has little to no energy hard points and i need it for something else. But if i can spare the weight, its well worth adding.
NARC
Locked on before you fire, and target is narc'd, I am not sure if you need to hold the lock or not, but holding your lock on a Narc'd target is about as easy as it gets.. just face in the general direction.. i can't recall if you can face in another or not, perhaps you can.. it's just been a while since I've used it.
Lastly
If you loose lock, the missiles no longer track and if they move you miss. You can however reacquire your lock and get um back on track.
