The description of ECM from the sourcebooks, instead of a wiki:
Technical Readout: 3050 Revised, pg 196
"The Guardian emits a broad-band signal that
interferes with all sonar, radar, UV, IR, and magscan sensors, thus protecting all units in a radius of up to 180 meters by projecting a "cloak" to its enemies.
Enemy long-range sensors can find vehicles and 'Mechs within the curtain, but the Guardian obscures the reading and prevents identification. By the time the enemy enters visual range, sensors can sometimes override the jamming, but by this time most pilots rely on their own eyes to track the opposition."
So sensors can get confused as the cloak interferes with data gathering, but it doesn't absolutely block tracking and locking like we currently have in MWO. This is supported by absolutely no rules saying ECM blocks 'Mechs completely out of radar, or interferes with LRM's. In fact, this is what the latest TechManual has to say about LRM's:
"Today’s vehicular-scale missile launchers are a broadly varied weapon class used to deliver clusters of self-propelled—and usually self-guided—munitions to a target. Not to be confused with capital scale missile launchers (or the Arrow IV artillery missile that will be discussed in a later text), the missiles mounted on many BattleMechs and Combat Vehicles are much smaller in size and power,
adapted to the electronic noise, limited sensor acuity and effective armor in the tactical battlefield." - TechManual, pg 229
A better way to implement ECM, which would make it more in line with the balance it achieved from the source material, and would still keep it useful (even against missiles), but not incredibly game breaking would be:
-- Disrupt blocks other electronic warfare devices like Beagle, Narc, Artemis, as well as shrouds information on the chassis such as damage and weapons loadout. Also blocks units within the bubble or on the opposite side of a bubble transmit target information, so spotters need to stay out of the bubble. (ref: Total Warfare, pg 134; Technical Readout 3050, pg 196)
-- Counter disrupts other ECM modules in range. (ref: Tactical Operations, pg 99)
-- Ghost Target mode projects false radar signatures the enemy can lock on that makes it more difficult to employ weapons like LRMs. Missile boats will need to cycle through false targets to find the target they are actually trying to shoot, and may even be fooled into shooting at false signatures. (ref: Tactical Operations, pg 100)
-- ECM can use only one mode at a time. (ref: Tactical Operations, pg 100)
Further balance would be to restore the Beagle Active Probe to full capability, as the Beagle can detect boundaries of ECM bubbles (pg 134, Total Warfare), more information from ECM shrouded 'Mechs, as well as identify ghost targets as being false signals (pg 99-100, 224 of Tactical Operations).
