As they gain power via leveling, Elite neutrals do not make sense from a game play perspective. Your average D'kora would have one of it's two abilities and lack either the missile launcher, or the ability added special properties on the rear weapon. Only if one were to suicide ships on them first to give them levels, would they be whole in function.
I wont rule out the possibility of leveled neutrals, but they aren't likely. Without the higher level AI functions, you really can't do anything with them. Even as a pirate raider, they have to exterminate their target before they can return alive with any experience they garnered, a rare event.
Ahhh, gotcha. Well, leave it as a big, heavy cruiser... I love it!!! First time I saw it I laughed, but just like the Ferengi themselves, don't underestimate it, it's a little bad asss!!!!!!
I'm still waiting for someone to make a Doomsday Machine.... even if it's just some kind of really rare militia to stick in an asteroid belt or something... something to mess with peoples heads if they saw one... hehehe.
Come on Mod team... you know you want to.....
