Choppers feel useless

I spend a lot of time being commander with a buddy and both choppers feel like they are bugged or nerfed.
They leave after 30 seconds doing nothing or they take heavy damage but do nothing most of the times.
It used to be an asset but it feels more like a gimmick at the moment.
It's like they don't actively hunt and just wait and leave.
After the last update they also stopped counting kills.

They are not useless, rather way too inconsistent. They can be incredibly frustrating at times and will kill your player instantly as soon as there is a window of opportunity to shoot, and sometimes ignores players or leave too quick if they start to take or consume too much damage
