Yes, the faster ship may be doing the dragging, but if MY tractor beam is bigger and latches on to him FIRST, I will be doing the rotation around me, so he will not be able to drop mines into my path.
Unless I am mistaken, He can not rotate me around him, I have the tractor on him to rotate him the AMML. Thus, I can stay out of the way of his mines dropping. I blow his shield and since he has no weapons, H & R his warp or impulse engine, etc.
Also, as he is pushing me and I rotate to keep him shoving me forward, I drop a mine and they hit him. I have done this before. My big tractor I latch him first, he pushes me but I lock onto to him first and I control him by rotate him and I stay in front.
He can not rotate me around behind as you say if I have HIM tractored. Am I missing something? Yes, AMML is cheese but the counter needs a big tractor and works....??? Someone tried this to me once and they never forgot it.
