It seems unlikely that increasing modern HI’s range would help them much while they’re still automatically selecting targets: in terms of damage dealt (but obviously not damage taken), this is essentially what moving them close to their target (as per the tests) already does.

Range would help with their survivability, but it’s an unfortunate situation where we have to try to somehow balance them around both automatic targeting (low DPS) and manual targeting (high DPS), which is essentially impossible without resolving the underlying target selection itself. If they were given, say, +3 range, their performance with automatic targeting would still be bad (better, but nonetheless poor), but their performance with manual targeting would probably make them overbearing, as modern HI (in range) can kill tanks faster than tanks can kill MI, or MI can kill HI.

Oh, I understand. Is useful to know that about about late game HI.

I’ve reduced the effect of the MI vs tanks thing in Alpha 10 with some related changes, but “fixing” it completely basically either requires making MI good against tanks (obviously completely breaking late-game balance lol), or reducing the focus-fire penalty significantly (which has far-reaching implications for combat in all ages).

The second is (as far as I know) a fundamentally hardcoded issue. It might be possible to implement some kind of very convoluted workaround but I don’t think it’s worth my time to explore it because it would be a lot of work without a known outcome. You’ll just have to remember to do target selection manually for late game HI.
