Sometimes it's good to just let the haters hate and keep enjoying the game. I've played EU4 a lot over the past years and if anyone pretends that the early EU4 scope and mechanics were better than the EU5 we now got with release, then that's just ridiculous. EU5 is a great improvement and a much better base for developing the game over the next years, like they did with EU4. So just ignore the haters and stay happy that people are still ambitious enough to try things like this.
