My attempt at Timurids-Mughals on the current patch, dlc up to Rights of Man. First I won the war against the uprising vassals and took a chunk of their land (cause you have cores there) and I took my Ajam cores back. Then I pushed into Delhi, formed the Mughals and mostly focused on India first. Only after that did I turn west to engage the unbreakable Ottoman-French
Aragon held almost all of Iberia for quite some time (expelling Castile to a few islands in southeast Asia and 2 African provinces though they did hold onto Alaska and California from there). Aragon had a PU over that Poland, they were my allies, as was Austria. Together we fought the Ottoman-French alliance and it repeatedly ended with my allies losing land as the Turks focused on them, letting my armies push deep into their lands and defeat them. Thats how the Ottomans took Vienna even as the Mughal west border was a stone's throw from Constantinople eventually. France crushed Aragon and Poland broke out of the union so I allied them later.
By the 18th century things got rather ridiculous. At one point I had 90% ahead of time penalty on military tech and the Ottomans were still a level ahead of me. I had broken their empire in two near Syria, hoping to make the whole south overseas. Even with that the Ottomans had insane amounts of troops (close to 400k) Eventually a war in the mid 18th century saw me victorious, occupying the entire Ottoman Empire and France. I let their war exhaustion skyrocket, then made peace hoping they would collapse from that. France faced a major revolution with a ton of rebels, but somehow they beat them back, restored the Ottoman alliance I had broken and the status quo was back.
Even now that I've taken Constantinople the Ottomans are still the most powerful nation on earth. Something is seriously wrong here. Do note below that my army sizee should be 350-400k but I just came out of a devastating war against Ming. I couldn't beat F**** Ming. I had closse to 400k men but disbanded some armies that were never going to reinforce.
Once I got set up as the Mughals I ran permanently with mercenary infantry, regular cavalry and artillery. Later I even made some of the cavalry forces mercs as I simply couldn't take the losses and even with max merc in my standing army and a near full mp pool, Ming still bled me white. Yes, really they forced my to white peace whilst I occupied half their nation. A better example of Operation Barbarossa you can't come up with. Was I wrong to use cavalry into the late game because of the Mughal cavalry bonus???
Regarding the income comparison: remember the Ottomans held most of the Constantinople node for most of the game and I only took control of much of that in the last few decades. Oh how different this could have been had I been able to break the Turks in the first decades............
(p.s. don't worry about Morocco, thats just Ashanti kicking their ass again)
