I agree that the BT and Dred combo seems non PBRish. I do know that as Klingons in all previous cycles, we enjoyed using the BT quite a bit. I know many of our adversaries hated facing it. As Gorns, we have used it as well. Most reason being that it can be hard to fill the BPV when it is high, and the BT(Klink is 192) allowed that to be filled.
So, for NEXT cycle, I propose the BT fall under the Command Category, with stipulation that only 1 tug per 3 ship combo be allowed.,
