Hearts of Iron IV recently received a new patch mainly focused on balancing changes. Several aspects of the game have been touched, starting with, players can no longer paradrop Medium and Heavy Flame Tank anymore.
Countries are now going to be a little picky as they are less likely to accept Swiss demands for territories anymore. Beating overseas countries with a Fascist or Neutral approach is slightly improved, and the Yalta conference will interact better with the new Peace Conference Format from now on.
You can read about the rest of the balancing changes below.
- Minor tweaks made to further railway/infrastructure focuses that were a bit weak, or were unchanged in the last iteration
- Changed certain Italian Balance of Power Decisions from being available only one time to once a year. This should give players more leeway with the whole balancing act
- Songgotu Zhanshan is now an economist for MAN to avoid a double Captain of Industry for MAN
- Reduced values for some modifiers in Swiss National Spirits, including Spirit of Saint Bernard.
- Reduced values for the modifiers in swiss Weapons Designer and Popular Dictator traits.
- Influencing Cantons decision in Switzerland is now slightly more expensive and less likely to succeed.
- Cohesion settings should no longer result in unit clumping for the AI, and provide a much more stable frontline situation for all orders with less relocation, but may have slightly more overall movement than before. [GD note: from a design perspective, cohesion now works significantly better than previously; feedback particularly appreciated here]
