i think for sake of simplicity. Take the amraam that is currently modelled and "just" make it better. In terms of reliability.  Better guidance, better intercept, better target track, better ecm, etc.

Better  - easy to say, on the end there is still a bunch of numbers, which of one has nothing to do with the other.

Well, we can treat it as an AMRAAM with a bigger motor and a better radar. I don't think guidance algorithms changed, and reliability is not modeled. If enough data could be found to determine just how much the motor improved, it could potentially be done.

Even B and also C5 variants are not modeled correctly. We are still missing the HPRF mode. When it goes active it only switches to MPRF (Pitbull) mode.

What it does IRL, after goes active, it switches to HPRF mode to lock on the target, and later on switches to MPRF. Only in case if very near to the target, it can skip the HPRF mode. But this is only in case if AMRAAM is shot from a shorter range to the target.

There are other things that should be fixed as well, like when IRL AMRAAM goes active it is almost impossible to evade it by using chaffs or evasive maneuvers, and also if it looses the lock, it will constantly try to reacquire, no matter what. Which is not what we have in DCS.

So ED must 1st fix our current AMRAAM - I hope it does, after so many years, I think its time to get it fine ones and for all - at least that it will work like it should work in publicly known theory (because we will never truly know how it works IRL).

That's not quite true, particularly with early models. While they will try to reacquire, AMRAAM's radar doesn't have a very wide beam. If the target leaves it, it will search and might find it again, but with proper tactics, this might require a sharper turn than the missile can make at this point (or rather, it will turn, but then fall short).

That said, it's definitely too easy to defeat, particularly considering lack of HPRF mode. TBH, I'm not sure if it'll go HPRF when it can, or if it'll continue under datalink until MPRF, like it does now, and only turn on HPRF in case the launcher loses track. HPRF does not have great tracking quality, and this would alert the target to the missile at an earlier point.

Plus, we need pullup cues on every FF AMRAAM boat. There is documentation on how it works in the Viper (A model, but that didn't change since), not sure about the Hornet and F-15, but there's no way it's not there. The fact that our DLZs are not exactly dynamic is a big elephant in the room by itself, they don't depend on launcher's pitch and seem to be unaffected by launcher's speed (drag is highly nonlinear in transsonic region, so it matters a lot on which side of it you are), only by altitude and closure rate. The actual missile is very much affected, so the DLZ will sell it short in most cases. AI should also learn to loft them.
