You've been at this for 5 years now. Aren't you tired?
Fact is, as i explained it to you before ( maybe wasnt to you); you never quote a war in which the Ottoman beat single handedly a major power. Funny to struggle against a point made, without answering to the point. Either its just a battle (great accomplishment), or it is just not against major power (ie, depending on time, Spain, France, united HRE, UK, Prussia/Russia by the end of the scope).
And sometimes, its Ottoman attacking, and beating Spain (winning a war! against a major ! single…. -While France is at war with Spain- ho shit)
During the same timeline, all those major power did beat some sort of other great power coalition. Ottoman did beat Mazovia and Albania. Congrats.
However, and that is a simple question, your alternate Ottoman Empire, that beat, in 17 wars, major nations of Europe, single handedly, in the spawn of two centuries, which is the straight "facts" that your post translate: how is it possible for him to need help from France and UK to keep some coherence? How is it possible for it to be bullied by Greece, Bulgaria, Romania and Serbia during the next century?
No country in Europe can brag about winning that much wars against its rival in only two centuries, and despite that, several strong independant nation were born or developped during this scope (especially UK, France, Prussia, Russia). What is amazing is that those less Glorious Nation, were never as low as Ottoman were after 1750. While, they were on a 17 win streak. Maybe they werent.
Maybe the truth is that Ottoman Sultanate was never able to rival any of those country, except, indeed, in some battles, or with the help of some major allies. Similar things could be said about Poland, Austria, Portugal, Netherland. Ive indeed said that for the last past 5 years (or so). And i'll keep saying it. But maybe you should stop saying the opposite, or try to demonstrate it, at least in our TimeLine. I dont know about your last EUIV run.
Because im some kind of productive; id propose to Paradox team (once more), to greatly nerf the Ottoman* and to pick one nation, or two, providing them with huge buff in each different games. The player would have a end game boss, but the game would all be different. As you dont treat Scandinavia, as Ottoman, or as rampaging Poland or wide UK. Now, its just without interest. Either you snipe Constantinople and keep Ottos in Check early game; either you have them eating half of Europe, 80% of the time.
*Id rather see them greatly increase the difficulties of ruling such a wide empire
Another possibility would be to block countries from sending more than Xthousand soldiers, Xkm away, except if they have some technologies or ideas etc.
Because multiple 30k European stacks in New World by 1600 is as ridiculous as Ottoman crushing major european nations.
