How is being shot out of the air while jet-packing cheap and nooby? AA's have their faults. When you look through that wall, you announce your position to everyone. When you fly up in the air, you can't maneuver as well as on foot. When you engage active camo, you announce your position. Skill is needed. Classic is just as cheap as modern. Classic: rockets/grenades and snipers rule. No easy evasion. Modern: Skilled AA users can counter these weapons and cause a need for more sniping practice. But the AA's have faults. Your argument is not fact and can be disputed and disproved. AA's are no more cheap and nooby than your Classic rockets, grenades, and snipers.
