Aleon, we have moved the discussion towards "how to fix", no longer "is there a need to fix?"
To enlighten this discussion, a short explanation on the lock range mechanics:
The biggest restriction there is view distance: You can only lock on targets that are inside your view distance. Viewdistance is a "sphere" of fixed distance per map, and it usually extends ~10% beyond the range where the fog thickens to full opacity (which is why you sometimes see tanks or choppers as silhouettes against the sky, but in "fog color").
And as you only can lock on targets that are rendered (= inside view range), both CAS and AA will only be able to lock on targets that are inside that range. CAS has a slight downside when hunting targets without a laze, because it will only be able to discern targets against the ground inside fog range, not view range.
The objective of this discussion is to refine the intended role of CAS as a hard-hitting surgical tool which is highly effective against armor and any kind of lazed target (or even well-reconed fortified infantry), but at the same time allow both infantry and vehicles a realistic counter. Which logically should be AA.
I think it makes a lot of sense to have CAS as a kind of "glass cannon": Every ground vehicle is scared endless of TOW missiles, to the point where you simply don't go somewhere because there MIGHT be a TOW. And: If you see the TOW, you are usually already dead.
CAS can swoop in and just say "Oh, there's an AA emplacement over there trying to kill us. So there must be a FOB nearby. Let's go there and kill them. Flares ftw."
Aleon makes a good point: Currently, bullets are the best counter to CAS, because you can't block them. However, it is ridiculous that they are actually more effective than missile-based systems. I'd propose to simply replace the absolutely ancient and outdated Strela/Igla and Stinger with newer systems, but that is unlikely to happen due to the need for new models and full code for them. "Realistically",
modern AA systems(as in: post-1975) wouldn't even give a missile lock warning for CAS, because they use passive seekers (most warners nowadays actually detect the fiery trail of the missile post-launch, not the lock-on). Let alone the many developments that are specifically geared to allow missiles to separate between flares and the actual target.
The simpler solution is to increase effectiveness of the existing means of AA. A reduction in sturdiness for CAS would be great, as it's currently too easy for it to survive a missile hit badly hurt and limp back to base. While bullet-based systems are non-deterrable, they also do very insignificant damage. Even heavy autocannons (30mm) require ~8 hits to take down a CAS. Doesn't sound like much, but it's very hard to hit a moving CAS in the first place. If you are stupid enough to get into range of a tank, it has every right to blow you to bits with a single hit. And if you stay in the range of a 30mm autocannon, it also should deal significant damage to you.
No other vehicle is granted this luxury in resilience. Even tanks more often die to a HAT hit than not, despite their HP being designed to barely withstand it. Since 1.0 even the new "heavy LAT" deals significant damage to a tank if it hits at the side/rear, forcing it to run for repairs.
Check
this video.
At mark 10:45 you can see the gunner spamming missiles vs a BTR. The reduced splash means the BTR survives for some time, but still it's a ridiculous amount of firepower raining down over the course of a few seconds. The entire video is worth a watch, a couple of awesome scenes in there, but also several scenes that show how carelessly CAS can be used currently.
tl;dr:
- Reduce hitpoints a bit (10-15%?) to turn CAS into more of a glass cannon instead of a flying tank
- Increase weapon delay between missiles fired (1 missile per 5 sec?) for self-guided missiles only to make the use of lazes more attractive again.
- Maybe: Reduce flare-spam (limit flare/second rate. Or deploy "flare salvo", then "reload" for x seconds for next salvo, opening a brief window for a well-timed AA missile
That would definitely be enough to both further the reliance of CAS on good intel while retaining their strength in LT mode.
To boost AA:
- Reduce time to missile lock
- Reduce "weapon ready" delay when manning stationary AA
