I will argue this again and again :P Clan Snow Raven wound up with the Potemkins because of several factors, only one of them being the transportation issues, if that were the case we would have only needed two to begin with and focus on getting some Black Lions out of those caches way back when, the Potemkins were more versatile than mere transports. I've put them up against Nightlords before and said, "Sorry Diamond Shark Player" because there wasn't enough of the Nightlord left to salvage for anything other than scrap. They have comparable armor to each other, but the Potemkin has a much harder bite especially when you consider that their escorts are Drop ships with ECM as well. We had 7 of these ships and one of the smallest toumans, we definately liked our combat. ;)
This trade was definitely NOT worth it. The Nightlord is okay, the Fredasa has it's use, but the Essexs are crap. Sure it's good compared to other destroyers, but compared to what we're giving up? It's got half the firepower and 1/10 the the armor! One Potemkin would take out two of them in no time and the Fredasa to boot :P Two Potemkins for all those ships would have been good. But we basically threw away a Potemkin and Volga in this deal.
