I must disagree with your argument that there should never be more than one weasel on a team. As far as Point Defense rushers go, weasel has arguably the best combination of maneuverability and energy, making it a solid rusher. On top of that, given that the rushing weasel does leak, it has the ability to EMP the enemies while repping them, doing tremendous amounts of damage with the Point Defense. Having three or four of these ships is quite effective, even moreso than other rushing ships, sometimes.
