Honestly, 1 pop abus seems like a thing of nightmares. Ottomans don’t need late game buffs imo. I actually made a thread somewhat recently where I pointed out that the historical weaknesses of the civ (one of which was always late game) have basically all been removed.
I think most of the nerfs Ottomans need are just to Azaps and their late game. Ottomans always were on a clock to kill their enemy or lose. That’s no longer the case.
