Well, i put one shipp to, very ancient.

This ship i used 1st day of MP, and during nex few months i achiaved score around 300:4 (all loss againts swarms).
Toughest (but most sweat)victory was definetelly agains ships using star war mod, huge ships, large shield etc, named Harbinger, with cost of 47 mill credits. Ovner of Harbinger it was really wery unhappy.
Change in game rules (new thrusters) send it to history of efficient ships, but even now, its still fun to play it.
After this ship, i made many builds, better, nicer strongerm, faster, but this one is ship, which was used in first hour of multiplayer.
