Look man, I kind of want to see the usual classic leaders come back eventually, but the way you are pleading your case by being incredibly dismisive of interesting characters really isn't helping your point. for example "The pirate lady" So should we refer to Suleiman as the Onion man and dismiss him then? surely you see how it sounds?
also, being a "ruler" in the classical civ fashion isn't the only thing the devs are looking at in civ VII for leader inclusion.
I mean I don't really like the Pirate republic, but Blackbeard as leader in civ VII absolutely works. and for a naval based DLC Sayyida is spot on, heck I wanted to see Zheng Yi Sao, but I guess her chances are dramatically reduced with Sayyida in.
I'm sure we'll get Suleiman or Mehmed II later on, but It's so clear they are saving a bunch of fan favourites for an expansion.
