Jamming:
Once you get LoS the jamming just disappears and never reappears unless you loose radar sight. Taking a look at the units that have Jamming (T2 Frigate, T2 sparky, T3 GS) none of them engages outside of jamming range. Only the frigate jamming might prove a tad bit useful when your opponent is to dumb to scout in mid game.
It's like you scouted a stealthed army once and can see it from there on.
Heres the idea. Unless you keep Line of sight, jamming will reappear. It's a fucking radar jammer, how does it stop jamming just because you had LoS once? It's a small change that will hardly effect T1 naval combat (line of sight range etc.). But it just might be usefull when adding jamming to other things like T2 gunships (sparkys on hook) or a T2 army.
Was just an idea, would be nice for the UEF arsenal to have a bit more e-war power. I'm not even sure if its doable, but didn't vanilla Frigates had permanent jamming?
