In my own opinion, a dialogue on how ECM should be in MWO has to incorporate several pieces of information. We can look at how it is currently implemented, and derive where it seems to fall short or overperform from that data. We can look at the original documentation from the rules set where it was explained exactly what it did and did not do to determine what parameters the gear was put into the original game to do.
The third piece of information is one that we simply don't have, despite multiple attempts (at least by myself) to do so. We need to know what the Devs intend ECM to be in their product. Is it supposed to be a cloaking system to prevent Scout units from detection at any but short ranges? Is it supposed to be an immunity shield against lock-on weaponry? Is it supposed to be an information denial system to prevent the enemy forces from getting information about their opposition? We just don't know, and the implementation of the system within the game seems contradictory to those goals (an Atlas is not a Scout unit, while Scout units are the least vulnerable to lock-on weapons because of their speed).
With the system being very light in both tonnage and critical space requirements, and having no cost in terms of usage difficulty or heat/energy usage, it makes the case that the system is not intended to be more than a light support system when compared to other support systems such as the Command Console, Artemis FCS, NARC, and so on.
So, the system must be looked at objectively within the scope of what it was originally intended as (a very short-ranged counter system to a few other enhancement systems...C3, NARC, TAG, and Artemis IV only), what the Devs intended it to do in their product (which they have never disclosed), what such a light system should be doing in relation to other systems in terms of cost in mech resources and pilot effort, and compared against its actual effect and performance within the game measured against those.
Until we have the information about the exact role the Devs intend for ECM, though, we will be missing a critical piece of information that will make actual recommendations lack full consideration of all of the facts needed. I would ask, therefore, that the Devs give us the precise intent of ECM within their game before we start trying to make recommendations.
