So I'm on a roll, ahead of the game having made alliances, happy population, then along comes the magical gift of the PC Ranger...to the Drengin and without taking even one hit point, it proceeds to knock out just about every ship I have.
I'm able to get every civ in the game at war with the Drengin but still the Ranger is toasting everything including my heavily fortified SB's.
The only positive thing is I am able to sneak a fleet around the back door and wipe out all the Drengin ships except the PCR.
So what is the Achilles heel of the beast? Even my lucky Ranger doesn't have a chance against it. It is definitely a wild card that you can count on showing up - usually with an otherwise losing civ.
