I just dropped 200 certs on an EMP Grenade only to find that it has no directives, no ribbons, and to get an assist the target has to die within 2 seconds. So why doesn't it have directives? No destroy 100 enemy shields, or assist 50 teammates with an EMP Grenade? EMP Grenades are great for Deployable Destruction, but the max I seem to get is about 1 Shield Regen and a Motion Spotter in really crowded areas. Sure people could just get 2 Infils from different factions get 2 Sunderers, and throw EMP's at each other all day, but people stat pad hacking and revives too.
