He's right about this, though.
Other than Northern Dobruja's shape getting changed waaaaaay at the beginning of tinto talks, I legit can't think of a single suggestion for Bulgaria which made it into the game, which begs the question what the point of these threads even was? I saw good, reasonable suggestions pile up in the eu4 subforum for a decade which never got implemented, so I figured it would be like this, but that didn't stop a lot of users from criticizing me for being negative before the feedback thread was out. Well, it's been out, and those same people are now the ones reassuring us that in a year or two paradox will finally get to fixing the Balkans. I get it, there's a subsection of users, high on hype, who will defend the devs' decisions no matter what, and it's not like most players really care about the map outside of Western Europe, but the way this whole thing was handled left a bad taste in my mouth. I just wish Paradox had been more transparent from the start about how willing they were to deviate from their vision so that I and a bunch of other people wouldn't have wasted their time reading and writing so much.
