I would not cite dark age feudalism with unsafe & unkept roads, no more running water, superstition, & illiteracy as "something better".
They couldn't even hold the land they stole. Vandals barely held Africa for a century before losing it to Byzantium, Odacer ran shit for like 5 minutes before he lost to the Ostrogoths who lost to Byzantium, Lombards came in and couldn't even conquer the whole peninsula in 200 years, Anglo-Saxons got wrecked by the Normans in 1066, the Norse "conquered" Iceland and sacked some monasteries, Visigoths let Muslims into Europe for the first time. Give me a fucking break.
Face it, the disintegration of Western Rome was deserved, but let's not act like what replaced it was better. Especially when these dummies tried to speak Latin and larp calling themselves Kaiser or Holy Roman Emperor. Fuck outta here
