You can just point me to the relevant patches, if you like. I don't mind doing my own reading, but PGI has always needed a database of current game rules - I shouldn't have to comb prior patches to find out how ECM works today. The game (or website) should just tell me. In any case, I looked over the patch notes specifically for ECM changes, but not knowing where/when/if they happened, I didn't find anything.
I don't know the patch notes that they changed in, I just know how it runs at the moment.
Without skills:
ECM prevents detection from distances of about 800-600m. It spreads 90m around (last I knew) to include allies nearby.
ECM lengthens missile lock times greatly when someone is trying to get a lock on an indirect ECM target.
It will still lengthen missile lock times with direct line of sight, but not nearly as much as it does for indirect.
Any enemy under the effects of your ECM will have their missile locking system turned off, just like previously. This means that, unless a SSRM boat (for example) an AP of some kind, they will be unable to retaliate back still.
TAG still "punches through" the effects of ECM, but it less helpful on the missile locking unit itself now than previously. TAG will still reduce lock times, but only at a greater distance (as ECM effects reduce lock times the farther out they are, as targets farther out naturally have longer missile lock times anyway). TAG on a support unit will make missile locks happen and act like the locker has line of sight to the target, even if they don't.
TAG still gets "disabled" (for all intents and purposes) if the TAG user is under the influence of ECM themselves. TAG will not permit, in above example, a SSRM mech to get locks while under enemy ECM.
With Skills: (As same as above, except with noted differences)
ECM prevents detection from closer distances, making a target "appear unlock-able" closer to 600-400m I believe. This effect, like above, is passed to any allies under the ECM unit.
So, essentially, ECM is not as powerful as it was in the olden days. It's still handy to have around, but it isn't as vital as it once was. Unlike previously, where one could stand in the open unafraid of missile locks (LRMs) if they had ECM, now you can and will very much still get LRMed. However, ECM makes it easier to jump in and out of cover to break or prevent missile locks (combined with Radar Deprivation and it can make it nearly impossible to missile lock effectively, even on an assault trudging from cover to cover), as well as prevent the floating IFF indicator to the enemy team on your position from farther away.
As mentioned above as well, a target standing in the open with ECM will still get missile locked rather easily, especially if the missile mechs in question have direct line of sight. At that point, ECM is only delaying their locks by a small margin. So ECM mechs are still vulnerable to lock on missiles, but have some small portion of defense if used correctly with taking advantage of cover.
It's interaction with NARC remains unchanged. Get NARCed with ECM, and your ECM turns off. If an ally is NARC and gets under your ECM bubble, it will disable the NARC as long as they remain under your shield.
