Very interesting and creative build. Congratulations for it.
I don’t really play Ottomans too much, because I always thought that this civilizations have a very predictable gameplay. With this variation I might take another look on they and see if I can find other builds that adds more versatility to them as well. Maybe they aren’t as dull and predictable as I thought they were. 
EDIT: I don’t know why I replied JonOli for this. I want to just make normal a post. How do I undo the reply thing?
