Helicopters in this game are fine if you want to get from point a to point b. they are atrocious to steer in combat situations though, making the miniguns/rocket pods useless.
Speak for yourself, I can use the weapons on them fairly well. Just an hour ago I was flying around in an Apache killing snipers in their watch towers without a struggle while my team was fighting the unidad forces.
Without an aiming system for pilots, helicopter weapons are just a guessing game. The Viper is a different story, the gunner can actually aim the thing... Sort of...
