What happened is that they did very well to start with, and when Crackshot came out they managed to hold on against the increasingly tough opponent ships. Their greatest stunt was that they were a pair of ships that threw 4-die attacks on offense, with a solid defense, with a large-based hull that actually cared about its arcs.
Then Jumpmasters showed up, and the deadeye torpboat that came with it was a trio of ships that threw 4-die attacks on offense, with a solid defense, on a large-based hull that actually cared about its arcs.
They're not the same, no, but the skills for one translate rather well to the other. And things just really haven't recovered since. They're probably not as bad any more, but... it's like flying a 7-8 ship TIE swarm. It's not that you can't , but it's only grown tougher as time has gone by, so only the dedicated fans are bothering.
