Absolutism will absolutely help you finish a WC more than essentially other modifier in the game will.
I never disagreed with this. In fact, I plainly stated that Administrative efficiency is the most powerful modifier at least twice. I'm not arguing that administrative efficiency isn't helpful. Administrative efficiency is great, alright?
But it isn't needed.
This thread started out with the premise that republics are bad because they have a lower absolutism cap.
But republics aren't any less capable of finishing a world conquest.
You can finish a WC with the absolutism penalty from republics.
So the strategies I mentioned aren't meant to replace administrative efficiency, they're just strategies that allow the player to finish a world conquest with less admin efficiency.
Yes, I understand that every one of those would be better with administrative efficiency, but that's not the point.
The possibility of a world conquest is binary depending on player skill, right? If I'm in a campaign, and I've set up a scenario that I can finish the world conquest at 70 absolutism, then going to 100 absolutism doesn't change whether or not I conquer the world. Absolutism let's me take more provinces, but I was already taking all the provinces. Theres a finite amount of land in the game, and once you have all of it you can't have more.
So if I have all the land at 1821 with 70 absolutism...
And I have all the land at 1821 with 100 absolutism...
Then in terms of
affecting the strategic outcome of the game 70 and 100 are exactly the same. Going to 100 absolutism did not change the outcome in the slightest.
That's why absolutism has diminishing returns with regard to its
value in determining the strategic outcome of the game. There comes a point when no amount of additional absolutism changes the end state of the world map.
So the real answer to how to not suck as a republic is to practice key, fundamental strategies until you don't need max absolutism.
