Dude, I have watched some of your videos and I must congratulate you. Your editing, your content and narration are impressive and one of the bests in the EU4 niche. Keep up the good work because I'm pretty sure that you can grow even further with your channel! Really well done, mate!
At last goverment reform you can wait untill admin tech 14 and you reform into horde, you can take horde ideas for extra 35cca (including policys, but you would have to take espionage ideas for one of first 3) and other cav bonuses. In the meanwhile you can expand as a horde, complete whole qara quyunlu mission tree, because the bonuses are worth it and when you can form persia you consolidate land you conquerd with reforming into persian goverment. I tested it in sp and it seems to be even stronger cav, than with sich rada strat. Aq quyunlu has basicly the same mission tree and its ideas are even better one of the best for cavalry focus
Would it make sense to form Georgia along the way for the fairly easy to get +10% permanent Shock-Damage modifier which works well with the additional 0.25 Shock pips you get from the AQ/QQ missions.
I did this to Eranshahr. It was very fun in that it essentially gives you two whole mission trees to complete, with great permanent benefits in both, as well as a whole host of estates (adds Qizilbash/Aswaran, Ghilman, AND Tribes), switches a whole culture group to another one, and gives you insane cavalry/infantry ratio and cavalry and artillery combat ability.
