Uh... why should scouts be immune to mines?
Because currently it's impossible to sweep mines without intense micromanagement.
Have you not run into >3k mines per gravity well yet?
Scouts also need for their detection range to be increased.
My personal theory for why "realistically" scouts wouldn't detonate the mines is that they're traveling fast enough to 1) not detonate the mines or 2) the mines are smart enough to know even if they detonate on a scout they won't catch it.
I base this off mines not detonating on fighters/bombers, and the scout is the third fastest unit in the game (barring Vasari speed buffs or Kodiak's ability), although it is admittedly much slower than fighters/bombers, so it makes a moderate amount of sense from a realism standpoint as well.
But, basically, scouts detect mines, so why would a scout run over one?
So in theory, it should detect and dodge any mine it encounters.
Explain to me how being immune to mines is any different than "dodging" them.
Maybe we're talking about two different types of immune, here. All I'm saying is that scouts shouldn't detonate mines. I'm not suggesting that they shouldn't take any damage from them.
If you'll read up, you'll see that I said that if another ship is accompanying the scout, it should detonate the mine. If a scout is in the blast radius, it should most certainly take damage.
