Just to be fair: pre EB 1.0, the Yellow Death played no role at all, everybody was afraid of the Grey Death instead.

And I must add that EB 1.2 is the best balanced EB of all times. Sweboz east expansion, Roman north expansion, Karthadast sand wars, KH eating up father Makedonia, Baktria overrunning the steppe - all this has been successfully adressed. What remains is just the Yellow / Grey balance and Hayasdans conquering the Sarmatians.
