The Ottomans are obviously an incredibly powerful civilization.
We have a unique trade landmark, the Sultanhani Trade Network, and can effortlessly turtle up, transition to farms, and boom our economy with Extensive Fortifications and Pax Ottomana.
Meanwhile, our Military Schools provide an incredibly powerful free-unit economy throughout the entire game, constantly pumping out Akinji that can simply kite the enemy frontline to death.
And of course, our late-game strength is among the best in the entire game, even without any additional economic technologies!
Truly, the Ottomans are the most perfectly designed civilization in AoE4.
Clearly, what they need is another round of nerfs.
