To make it possible to “fight” against the only thing I could think of was that the units wouldn’t show radar signatures if in the fog of war. I wasn’t sure if it was actually possible to have an icon show up in visual range but no gray dot show up in the fog of war, but that would be a great solution and would make you curious if maybe you just missed the units before your scout went over them.
Cybran build drones are units to some degree and they do not have radar blips. I think this is possible, but I'm not sure what the side effects are. I think it is the INSIGNIFICANTUNIT
causes them to not have blips, but I'd have to check and confirm.
Note that blips (even fake ones) are entities to some degree, they impact the simulation rate. A massive increase of (fake) blips is not preferred. Spikey has been working on making the jammer more useful by auto toggling it when the unit is out of vision again: https://github.com/FAForever/fa/pull/3927
And to your idea, it feels to me that:
- Aeon should get more vision-like capabilities, as they have the Quantum Optics Facility. As an example: have the projectiles of their t2 destroyer, point defense and t3 battleship give a small amount of 'true sight' on their impact location. Their torpedo bombers already do this for underwater units, it allows you to spot submarines with stealth
- Seraphim should get the 'fake' units that you're talking about, as that fits with them having 'alien' and unknown technologies
- UEF can maybe get a land-based deployable jammer that can also introduce fake air unit blips
And with that said, I think UEF units should no longer give vision with their projectiles (their lobo's do that, as one example).
