WoW, I thought you were kidding until I looked it up. Mandrill ships DO suck. The only ship you have of any worth is the Potemkin. The stories make the Soyuz look like it's a top notch ship, but it's only so so. It's slow, had moderate armor and weapons. The only thing that makes it nice is that it's got lots of Docking collars and a decently low BV value. However, for about the same BV, you can get a Potemkin which has better Armor, Weapons and has more docking collars, but people won't use it for fear of losing their MP Bonus
Not me though
I love getting my Potemkins into battle
The only potemkins I lost were to nukes and horrible dice not being able to save them.
Anywho, that being said, I agree with your assessment, the Blood Spirit Navy would have the upper hand in a trail between the two. The only bonus you would get as a mandril is in numbers with the stacked ECM bubble. If your Soyuz / Potemkin could roll enough on the ECM, they might be able to last long enough to take out that Black Lion. but even then they would probably still lose overall due to attrition. At the same time your trying to take out one ship, that Lion / Aegis combo would chew thru your escorts and eventually your Potemkin.
Or at least that's how I'd do it.
I wish we were able to get the plans to some of our smaller ships. I actually liked the Nightwing. Better than the tracker and with the same general capabilities. It's a surveillance ship I'd take over a Vincent, Carrack or Tracker. I think the Falcons got one of the best bumps in the game when they got the design for the Quixote. It was a great ship for very cheap due to the KF Engines. We purchased so many of those from the Falcons before they turned on the Clans.
