I too had to remove ships from this mod. The large IED ships are, in my opinion, to swingy. I've tried to stop them by swarming them with small disposable ships, but they are too effectively screened by the other ships. I have yet devised a strategy that reliably stops them. It turns Ludd pather encounters into a roulette wheel of costly supply and crew losses as well as D-mod gains. I've hear they pernitrate shields too which is a questionable discussion. Would it not be better for them to have to overload shields first? That way after the big ship explodes the smaller ships can swarm the opened capitals. This at least give the player opportunities to save the overloaded capitals. As it stands they pretty much just delete any slow moving capital which is not very fun. IED ships do totally fit the Pather lore though, so I would love to see the larger ones better implemented.
