Yeah, peaceful Denmark will suffer for the most part. It's just that the way I see it, one part of the UA used to be actually somewhat Unique along with the Ottoman Sipahi. This is now technically nullified thanks to the Landsknecht. The UA still works quite well if you warmonger like Ziad wrote, it's just that perhaps Denmark should get one little extra thing in their pillaging, making their pillaging just a little bit more powerful, so it stays with their playstyle. Perhaps a little experience on pillage or 50% more gold from pillaging? Because let's not forget; Pyramids+Citizenship equals repairing improvements in one turn. This can potentionally lead to pillaging a tile, have your worker repair it, and pillaging it again! No movement cost involved and you're 50HP stronger and got some extra gold in your coffers. Heck, with enough workers, all of your units could have a March promotion without having it!
