Baiting exist for a reason. This doesn’t just apply for helicopters you know.
In addition, not all maps include physical barriers that prevent the missile from reaching you for example. If you are hiding behind trees, the pantsir’s radar can still track you (or at the very least give occasional locks which can allow the missile to directly hit you.
For the maps that do include a physical barrier, most of the maps, require you to climb due you becayse you need LOS of the enemy. When you climb, your chances of getting behind cover, or loosing the SPAA loosing lock decreases significantly.
So again, this tactic only applies in certain maps and even then you are still vulnerable.
You do realize that both teams has FnF helicopters? You keeping the pantsirs at bay doesn’t dismiss the fact that mi28 can reliably take out SACLOS and FnF spaa. One side has better advantage, than the other.
For the JAGM to be used effectively, it needs direct LOS of the target it doesn’t loft nearly as much as the LMUR. this means that any bushes, cover, or of that sorts will prevent the JAGMs from hitting the target. this applies to the majority of small-mid sized maps. To prevent this, you need to climb which will put you at significant risk.
If they don’t launch all 16 at once, then you can replenish them. Like you said you have 24 missiles total which is more than enough to keep enemy helis busy for a while. 16 JAGMs are only good if you can launch a lot of them at them at the same which is difficult when there’s a pantsir. If you can’t, you might as well use LMURs.
Ba-11s are more of threat the JAGMs for this very reason.
You shooting down munitions and keeping enemy helicopters at bay buys your team time to cap, kill enemies, etc.
It is significantly better than any SPAA in the game because it can counter helicopters and munitions. It doesn’t help that we’ll be getting a even better pantsir that will almost certainly get rid the majority of tactics used by helicopter players due to it’s time based fuze.
My guess on why the Mi28nm performs a lot better than the Guardians is because of this very reason. If there was no enemy pantsir, you can away with a lot of things in the gaurdian, but with it being present in almost all games, it forces you to play patiently and smartly which isn’t ideal for the short and fast paced nature of games.
