Just had an idea since this topic is also on for a longer time now how to improve jamming. Stealth has the problem that you can attack units and enemy units will keep attack order while beeing under stealth. But if this is fixed that might be even imba. That could make cybran army with bigger range invulnerable if you lost air sup. But stealth has at least an effect compared to jamming. Scu jamming is bullshit and all other jamming are just there but without any use. Jamming would be more useful if there would be some kind of reset which makes units in radar range but not omin range unknown after some time again. Means that jamming would not be stealth but from time to time reset the jamming mirror pictures to appear again if enemy does not scout and the units which are seen will be unknown again.
I dont know how long stealth needs to be active that enemy loses the targets again but one way for jamming would be that jamming includes a pulsed stealth for example. For example uef t1 friagte has jamming and every 10s it has a pulse of stealth for 0,5s so the units in radar range will for minimal time disappear and also mirror pictures reset. That uef will not start permanent stealth with frigates you could add higher e cost and switch it off by default. So jamming would be some kind of mild stealth. And for scu for example you can do different steps of jamming. So maybe scu jamming would have much lower reset time or maybe even 1s stealth time pulsed.
That could be btw an option for UEF Acu. instead of nano which is no matter how you balance it will be a bullshit compared to t2 engi maybe remove this ability and add jamming there. Uef needs an not op early game option there. So uef can have gun and instead of t2 engi a cheap jamming suit alike cybran stealth and gun. Jamming like normal units since in late game there is no way arround engi suit. Maybe somebody can use this idea to invent even something better alike
