Sure after 1600+ hours playing the game unlocking knowledge levels PER ship is untenantable. It feels like I have to level up again, when I spent so much time getting to Rear Admiral. It feels like the developers lack imagination when creating game content and have resorted to making it a grind fest instead. It is a serious problem when it takes over 40 hours of game play to unlock all the slots on a 2nd rate.
I think it would be better if they fixed the open world tagging system, and worked on improving trade and commerce making the game more customizable and interesting.
