I cut "air superiority" out. You're right, although there is still a little room for arguement.
About fighters killing each other : it happens.
Not a lot, but it happens. Often enough when you're on "equal" terms.
What almost never happens is saminf shooting down planes AFAIK.
But if you try to have "air superiority" from the ground, you're obviously wrong, don't you think?
Yes, I don't mind that the SAM inf (or Mech Inf) doesn't shoot down fighters. They should primarily be a unit that defends against air strikes and thus damaging the air attacker and preventing bombing damage is ok. An occasional lethal encounter would be enough. But fighter-fighter engagements (and attacking bomber-defending fighter engagements) should be far more lethal to avoid making it attractive to even attack heavily anti-air defended cities.
I would propose that fighter-fighter engagements are lethal in 50% of the engagements and that the defender wins in 2/3 of the engagements while the attackers wins in 1/3 of the engagements. Now the lethality is below 10% (according to the test I did in vanilla 1.52 a half year ago). That doesn't deter any air attack.
