@TheMeInTeam : Interesting. Was there a specific reason to rush west? Cut off colonizers is outdated like cut off Russia and it also does not look like you wanted to snipe the unify-Islam provinces early on.
No, going west to that extent was not planned at all. I did want to unify Islam whenever I could, but after tearing up Maghrebi a bit to manage coalitions (Sunni world hated me, I was going all-in AE on them and keeping other groups < 50) it was one of those situations where Castile had no allies and ~10 regiments due to a bad war.
If it's going to be offered on a platter like that you might as well take it

Holy fucking hell all you've done is inspire my to throw my computer out the window.
There are players out there (and in this thread) who are significantly better than me too, the important thing is to think about what different choices you can make to match or surpass.
Also, you don't need this kind of progress just for world conquest. I was going for Sunni one faith (IE all provinces in the world Sunni) + being the only nation existing in the old world, no vassals.
Do attempts, make + find mistakes, correct for them.
For a more concrete question, I switched Coptic on a ref run just to see how to do it. I can see how 10% CCR stacked on Ottoman idea and Admin can be huge, but does 2.5% Disc and the manpower recovery outweighs 10% morale from pius Sunni?
No, Sunni is the better combat faith. If you're going Coptic, you're doing it for the 10% core cost, possibility of PUs (not a big deal but can help some runs), and becoming HRE emperor if you get the Westphalia outcome in 30 years war. Troop quality isn't too important late game though.
Coptic route loses the Ottoman government. In the long run you can probably save more points with the 10% core cost reduction (that also speeds up coring so it's helpful) but for the early going's before you can perma-100 prestige not having the choice of 3 heirs per disinherit is noticeable. Coptic, Sunni, and Catholic Ottomans can all hit world conquest much easier than most other nations though.
As for neat borders, that usually sorts itself out when you're the only nation on the board, which is faster when you gut out all those annoying forts ASAP
