The following is a guide on how to properly use and leverage the stealth tower well beyond any in-game means to counter it.
Terraform a High point, Place the cloaking tower in a basin to the rear of this high point.
Wait for a enamy.
A enemy with a force of 50 shows up to take your OP.
Fit a ictus with all neut tuners and RE's in the head slot supported by a injector bot w/ RA's.
Fit a couple seths with 900m Range
Fit a couple Vagabonds with 900m Range
Ignore any need for defense in your leg slots, Stack hit dispersion and recharge to have as much up-time as possible.
Now with the current stealth mechanics a robot that is stealth that encounters a enamy who is not will only see the masked bot upon a completed Lock.
What does this mean?
As the attacking force if you attempt to send any shield bot forward realize that you are unable to stop the ictus from neuting 4500 a savlo with out reactor sealing. Further more the e-war under the cloak will be able to freely target your support bots and perma jam them with out fear of enamy e-war intercepting them as they can only be seen by the target they have perma jammed.
Thus the only effective way to attempt to close the distance would be a Terraformed bunker push on the base but your terraformers may be unable to lock any tiles to terraform and should you get close enough im sure a couple mesmers fully tuner fit with gauss guns salvo'ing your fleet from safety a mere 200m away yet you cant see them till under 100m would/could/will keep you away.
Its that there is currently no method to counter the proper use of the stealth tower.
Obviously if no one is home you can kill it but i would say if no one is home they shouldnt be on gamma.
