I want to thanks the admins for move this post on the Suggestion forum, mean maybe a day they will release a patch for fix that ( I hope )
I want also to remind the topic of this post: it's about the port bonuses and the DLC ship. For talk about how powerful or weak are the DLC ships there are other specific topics.
In the game every ship, crafted or DLC, can have random buff like "Very fast" or "Sturdy" or so. And every crafted or DLC can be in quality blue, purple or gold.
But only the crafted ships can have the port bonuses while the DLC no.
Maybe the devs forgot this thing ?
I hope they will fix it soon
