As someone who's on the fence about this game this worries me. Care to elaborate? Footage I've seen doesn't seem to have much variety in the combat, with almost everything missile based and hardly any use of cannons. I've seen precious little air to ground bombing raids either.
Clouds look amazing though, almost tempted to buy on the strength of the graphics alone!
The game relies on various objectives for variety but the gameplay itself has just been a mix of dogfighting and ground targets. You're constantly under missile lock and in danger of stalling so gameplay turns into lock-on > fire at target > maneuver to avoid missile > lock-on > fire at target > maneuver to avoid missile. I also think that some of the mission objectives could be tweaked to be less frustrating as well.
