Crucifier looks great, maulus decent. Friggin Griffin (had to!) looks a bit overpowered, not because of the ship's bonuses, but because I feel ECM is overpowered.

Why not add a new ECM statistic: "Jamming Duration". Say an ECM module's cycle time is 30 seconds, its "jamming duration" might be 10 seconds. Thus, there is a 20 second period in which the targeted ship can lock during each cycle. This will allow the jammed ship(s) to fight back to some degree, without heavily nerfing ECM. Being the E-War race, Caldari will still retain the power to immediately disrupt the operations of an enemy force, but make them less useful in prolonged fighting.

This change would make ECM less effective against smaller ships - a small ship will have a low sensor strength, so it will still be initially jammed, but it will have a high scan resolution to relock after the "jamming duration" is complete. While a single ECM ship is currently able to "perma jam" 4-6 frigates, it would now lose the ability to keep them jammed. On the contrary, large ships have more sensor strength to prevent jam, but once jammed, will have greater difficulty locking the ECM ship. Marauders will still 100% suck vs ECM (lol).

If this change were implemented, I can foresee the idea of "staggering" the cycle of your ECM modules so one activates at the other's mid-cycle. Even still, this change would effectively double the amount of ECM needed to "perma jam". Or, it could force "solo" pvpers to bring in their arazu alt (scan res sensor damps), in addition to their falcon alt, in order to beat that one missioner. Looks great on killmails, really!

If nothing else, the falcon would be forced to fight more like an ECM stealth bomber, especially because it would be particularly vulnerable to high alpha weaponry. And holding range will be more difficult for ECM ships, since MWD inflates sig radius, making it easier to lock during the ecm cycle's off time.

And heck, vigil pilots won't be primaried, so they can use their badass TP bonus on an ECM ship, making easier for their buddies to lock him mid cycle ;D
