Ghost ship spawns - should be unleveled

[Ukase]

I was grabbing the explorations on a level 30 controller in Indy port, and happened to see the Ghost ship about to exit. It left behind, as it is designed to do - ghosts. That are level 25. 

This doesn't make much sense to me. It seems like these should be unleveled, the way the snowmen that spawn from Christmas presents are. The badger in me hates the idea, because it means I'd need help, most likely, to get this badge on my controller, if I wanted to get it quickly. 

But damn, I was 1 bar from 31. Might have been nice to knock those 50 ghosts out, get the badge, and maybe get the next level. 

Is there a reason these are level 25 npcs instead of unleveled? Or have our brilliant devs just not gotten around to it yet?
