Personally I find it even easy in a CAS Huey on Muttrah. Sure I die, but that's to be expected.
I really don't want to play the muh realism card but in a way CAS was (and in certain hands) is unbelievably strong. Have you seen near peer air engagements? If the game does not offer the level of detail in how missiles lock on and make real life evasion tactics usable then I'll gladly take a frustrating RNG'ed moment over easy CAS kills.
I mean let's look at the deaths in CAS: Overextending, kill greed, lack of mapknowledge, lack of info on mobile AA assets, false intel, smashing into the ground are what I deem the reasons to why you and I die. If all those factors are minimized we can talk about reducing bot AA assets.
If you expose yourself too much you take the risk. And every PR coop CAS pro does that.
No disrespect, but show me a clip of a not fun death in CAS and we can analyze what went wrong. Otherwise this, like many other posts will go nowhere.
