Kyo how come that you have specificaly addressed Turkish faction? hehe

I would say that Turks are playable in high era and even in late. Overall I agree that there are factions which are considerably stronger then others ( based on the unit tpye selection criteria ).

Turkish hybrid infs missle stats should be made better in order to balance their force with western inf.
Despite few of their infantry units like JHI are probably the strongest infantry unit in the game, they have poor infantry selection overall.
