Believe what you wish, but there is no way over torquing your wheel lugs is going to warp a rotor.

The wheel stud attaches to the hub, not the rotor, the rotor sits flat against the hub, sandwiched between the wheel and the hub. If you were able to exert enough torque by over torquing, you would distort the hub not the rotor. Secondly if you did warp the rotor in this fashion, you would warp the mounting surface, and turning the disc would not cure the runout problem.

There many reasons to use a proper torque wrench to attach the wheels but warping the rotors in not one of them. Now if you under torque the wheels, the rotor could distort under braking forces if not clamped with the correct force between the wheel and hub, which will lead to damage.
