Thanks for the positive support guys! Maybe they will come round to their decoy building idea. Will add a lot of interesting gameplay dynamics.
@dinner: My thought was that it would mimic any structure you wanted. So if you had levels 4-5-6 AD's you would have to pick which level would serve as the "decoy" ... gives people incentive to develop their base better. Because if you see three different levels of things then you know at least 2 that are real, etc...
