In all my time I played EU4 I never really gave my self the effort to breakdown all the things that make my army strong, all I've taken with me is that:
- up-to-date military tech is a must (because of tactics/morale or something)
- super high morale makes me stake wipe the bad People
- discipline reduces causalities (?)
- combat ability increases enemy causalities
Now while these are the basics (right...?) I was wondering what else I could do to increase my military forces. For instance am I currently playing as Prussia and all I really did was focusing on stacking morale with my advicors and a military policy. As it happens I noticed that I could also stack extremely high infantry Combat ability (20 from Prussian Ideas, 20 from quality and another 10 from a policy).
Now I don't know what my benefit would be, which is why I am asking this.
Which military thing is best to stack and whats the impact? Is it perhaps better to mix it or just go all in on one modefier?
Is there perhaps a thread that deals with this topic?
Thank you
