Do you think Grrm kinda botched the dothraki in military terms, since irl the nomadic armies tended to be rather innovative? I realise that the mongols are an exception (as allways), since they conquered very advanced civilizations which gave them a massive boost in siege warfare and general know-how, but 10th century hungarians, without any of that displayed enormous cunning and a depth of understanding of warfare, take their campaign against King Berengar of Italy, where they even

they even managed to assault Venice, though unsuccesfully, with a mounted army. It is just beyond belief, that for centuries, their tactics would only regress, given the near constant infighting between the khallasars. Or alternatively, not one of the free cities got a leader with ambition, or a temporary lack of funds with for tribute would go and beat them in the many, MANY ways they could be beaten? That say, after the performance of the Unsullied against them, no one of power ever

ever thought it would be cheaper to beat them once soundly, and get free of them for a generation or two? Essos supposed to be the advanced continent after all.

I think the issue is that GRRM wanted the Dothraki to be a huge potential threat, but didn’t want them to have conquered Essos, so he needed to find a middle ground and so gave them a couple flaws so that they wouldn’t have overrun the continent. 

But not every nomadic army is particularly innovative. Some just come and go.
