The boost, break through one ECM. It really wouldn't be that hard to code in IMO as it's already in place where an ECM on Counter breaks through an ECM on Disrupt. Like with ECM, this would create a tactical element where another ECM unit would have to move in to shield the NARCed mech.
The small tweak I would give this would be a 10% decay per second after the 20s. This decay can be countered by ECM. So the NARC broadcasts for 20s on an ECM shielded mech and up to 30s on an un-shielded one.
The 20-30s time on NARC isn't that bad. At the MAX range of LRMs (1000m), allowing for lock (3s) and flight time (100m/s) this gives the chance for up to 3 full bursts (counting for tube count and the .4s impulse time). This gives the opportunity for one full volley on an ECM shielded mech and two on a mech not under ECM.
