Ever since sniper towers were introduced into Dominations, attack helicopters have been fairly useless. The helis have the longest range of any unit, thus sniper towers will naturally target them first. Given their low health, they go down quickly, and we can no longer take 6 sabotage into battle to counter sniper towers. Decoys won't work well because you have to place it right at the edge of the tower's range, and as the battle moves, they decoy no longer is useful. If sniper towers were made to ignore flying units, they would be much more useful.
