Don't get me wrong. I have a healthy respect for tractor beams on my opponent. But I think it's easy to play smart enough to overcome the issue.
That and right now it's only in the ISD pack (I could be wrong...I'm a little poped up on cold meds). I don't think too many smart fellas are going to run more than 2 and unless you've got deep pockets, probably won't buy more than that anyways.
Tractor Beams are good and I will keep saying so they just don't provide a threat that worries me. That's the important part. I am not looking at the upgrade but more at the ship it is on.
