I'll just leave some thoughts here.
I am glad that someone from Paradox finally responded to this thread. As I felt this is something that needed addressed. However, it took about 2 weeks for a response to this, or similar complaints. That is bad. I'll explain why.
The first dev diary after the release of the patch/dlc was a disappointment for me. You release a fairly large DLC and patch, and the first dev diary was about funny looking lakes, a RNW that doesn't work as good as you want, and hot join being broken or not working well enough. Basically old issues. Nothing at all in the OP about the more recent stuff. Nothing addressing any issues people had.(not counting the hotfix to fix a few technical problems)
To me, and few others I know,(i know not everyone) this seemed like an intentional dodge. It felt like if you ignored the issues, and hoped the issues and the people bringing them up would go away. This may not of been your goal. but when you stay silent on an issue(s), and talk about very low end issues rather than the more recent larger issues in the "official" thread, this is how it comes across. It shouldn't have taken 2 weeks to give the above response imo.
and after reading johans response, I cant tell if he understands where some people are coming from in regards to buildings and development. I would hope he does, as if he doesn't after reading all of this, I am worried about the future of EU4.
Rob Roy said it pretty well. and there are others.
"Some people, including myself, bought the DLC on day 1, but still felt putting Development behind the paywall was inappropriate (not because of building slots but because CS removed the traditional means of improving provinces' manpower and base_tax values while restricting access to the most analogous replacement system)."
You can now only do some of the things that the buildings use to do, unless you own the DLC. You redesigned the whole game around this new development system with no way to manipulate it outside of events.(which buildings use to) Not only that, you removed all of the unique buildings, and are only now getting the embassy replaced.(partially) the building slots is another problem in some parts of the world. not to mention a good way to sink access MP points before CS.(which you are bound to have in. more in some parts of the world compared to others)
I am someone who thinks this should of been in the patch, or have all of the new buildings/dev system in the DLC(in a way like the older expansions), and let those without it have the older buildings. You replaced a working older system with a half of one given out, the other requiring money.
I know there are a lot of people who both like and dislike the new system being put in a dlc. I don't expect a lot of people to agree with my views, but i felt it must be said. Now it would be nice if Paradox came out sooner explaining their thoughts/reasoning behind their change. Even if i disagreed with it, at least I would know. at least I could tell my friends about your reasoning. up until today, all i could say is they are ignoring people's concerns on the subject. and while i know it is unreasonable to expect an answer for every concern, the major ones like the above should be acknowledged.
I would also hope that he knows that not everyone who buys a DLC likes/agrees with it. Unless that is the only thing that matters. I would hope not.
I have some thoughts about the patch as well, but i'll save those for another time and thread.
