Let's say that during the third century, different series of crisises and events in the Roman Empire left the Western parts of the Roman Empire stayed strong, while the Eastern parts ended up weakened and impoverished.
So Germanic tribes like Franks, Goths, Vandals, Saxons, Angles, and Lombards ended up taking the southern route, moving through Balkans before trying to settle in Anatolia and Mesopotamia (instead of Western Europe).
What is the likely effect of this migration to Eastern Roman Empire instead of the Western parts?
