I don't really see how this is a "hot-fix". In my mind, a hot-fix is a small patch that only addresses a few game-breaking issues. Adding features and mechanics and tweaking game balance is not a hot fix.
Believe me, I love new features and mechanics, and it's fantastic that Paradox does such a great job of giving us extra free content after release. But new features and mechanics needs to be tested. They shouldn't be shipped out in a hot-fix only to have it turn out that they're half-baked and broken. Keep the new things in your pocket for a tested, polished patch release, and save the hot-fixes for game-breaking bugs.
As it is, these are having the opposite effect. I've gone from a perfectly enjoyable game under 1.05c to being locked in an un-endable war in 1.05d. If your hot-fixes are introducing new game-breaking issues, that's a big problem.
