Radar dampening really has spread too far. It started out as the SSB's gimmick and now it's everywhere...
I don't think this assertion, though somewhat common lately, is helpful or accurate because Radar Dampening is not actually on very many units (certainly not "everywhere"), and it has a specific purpose for being there in most cases.
It's on:
All guard posts except the SF post and the Spire-Shield post (which I think technically has it but it doesn't seem to keep stuff from shooting at it from wherever anyway).
-The former I should just rename "Special Forces Rally Post" because it's not really like the other guard posts and hasn't been for a long, long time. The Spire-Shield one is a ff-emitter and those generally can't be dampened.
- Anyway, these have RD for a very specific reason: to make sure you have to actually engage them rather than just snipe every single one from outside its range. Arty Golem aside, as it's a superweapon that specifically counters these (and a few other units serve the purpose pretty well).
Turrets (mkII+)
- Similar to the guard posts: because its a stationary defense that "snipe from range, all day, every day" doesn't make particularly interesting. But it's less essential since the AI is less deliberate about that sort of attack than humans are, so this was given to the mkII+'s as a buff to their desirability.
Raider Guardians (including Dire)
Raid Starships
Spire Stealth Battleships
Space Planes
Neinzul Champs (mkII+)
- This is to facilitate the raiding role: part of the point and value of these units is to be able to go after targets without all the planet's defenses being able to engage them.
Flagships
Mobile Space Dock
Enclave Starship
- These are basically "officer" units that are very helpful to keep moving around with (or slightly behind) your main forces, but if the enemy could shoot at them as freely as they could anything else then these would die really quickly and thus lose a lot of their point.
Mining Golem
Resistance-Fighter faction ships
Marauder faction ships
- These are minor faction units that spawn way the waaaaay away from the planet center. The RD just lets them close (in theory).
Scouts/Scout-starships
- Just to help survivability while moving through enemy defenses, because that's basically all they do.
Fortresses and Mod Forts (but it's 30k range)
- This isn't really even normal radar dampening because the range is so enormous. It was added by request, I'm not entirely sure why
Hive Golem
Spirecraft Siege Towers
- Ok, I'll give you these as not really making a ton of sense to have it. I mean, the Hive could fit in the "officer" category but it doesn't actually do a lot of ongoing deployment so you can just keep it back. And the Siege Tower could fit the "raider" category but it lacks the cloaking and/or (iirc) speed for that to make sense.
Anyway, I'd be happy to drop it from the Hive Golem and the Spirecraft Siege Towers. Even the forts unless someone objects (though again those ranges are so huge, is the RD really noticeable?).
But what else would you want it to go away from? It's really not on all that many units.
