As I play Civ V, I find myself missing having multiple leaders per civ as was the case in previous iterations. It seems that instead of adding more and more obscure civs, the game developers should look into adding new leaders for existing civs. Most civilizations have had many interesting leaders with diverse personalities throughout their long history. How about bringing back Stalin for Russia or Mao for China?
This also helps avoid incongruities such as Napoleon, who is famous for his military prowess, being given a cultural focus and UA simply because France is more known for being a "cultural" civ.
I personally would prefer buying DLCs that added new leaders to existing civs with their own UAs (the UU/UB/UI can stay unchanged), rather than DLCs for new civs.
