Will they kept their own culture, at least until 100 BC? Development of religion, language, social stratification and... government. If is impossible to develop a state in the steppes at this time, they must conquer an area for capital. The location of this capital will be decisive for future development of mankind: for avoid a Persian Empire or a Greek Empire or whatever civilization like TTL, can be the Indoeuropean capital in Crimea?
