Yea its wack. The helos need to circle around and not sit still, and also should only be viably taken down by rpgs. For minigun support, the door gunners should be hittable, so that small arms fire could potentially neutralize a door gunner or two, but not crash the whole helicopter.
The worst part about this is that the choppers almost always go down ONLY to bullet fire, not to RPGs. It's because with the hitscan weapons and the bot aimbot...they just pepper ONLY the choppers rear rotor (a weakpoint) with 100% accuracy until it falls from the sky.
We figured this out.
You call it in miles away from the enemies. As in, if you're defending G, call it in at A.
The gunner spends more time with arcs on target and actually racks up kills. The heli tends to survive its entire strafe. We've tested this tens of times, it's fairly consistent.
Would recommend its use for defences ideally which maximises the chance it will have things to shoot at given at a far distance / angle it's going to have fewer choices of targets unless they're all scurrying around trying to get somewhere.
its the same with the IED drone call in for the insurgents, instant take down on bot maps making them completely useless..... I do feel that the Security forces do need another call in perhaps a reaper drone that sends missiles down as another timed support call in similar to the gunship but limited to one per round.
