Things I should be changed for better in the Essos plot:
A slave revolution and resistence should already exist in most of the cities.
Estabilish better that Daenerys grew up in Essos even if she was born in Dragonstone, her antis are all like 'she is Westerosi, she is a foreign ruler and racist agaist Essosi' and at same time 'she didn’t grew up in Westeros, she has no right to want to rule it'???
Many of those slaves are not Essosi/Ghiscari either??? Some are from Naath, Westerosi, Asshai, Valyrian, Dothraki...
Political Conflicts in Essos Nobility that has nothing to do with slavery, like a sucession crisis, two rivals families feud, a usurpation, a fallen family (why I am thinking of Troy? I just read a deep analisis of the slavement of trojan royal family), crazy harem dynamics (Lynesse Hightower!!!), noble ladies and princess of Essos, even some greek-like heroes and 'demigods', a few wars and battles not involved with Dany or slavery, just like we have in Westeros.
More about the fact Westerosi was already Stolen Land before House Targaryen come, House Stark were colonizers before. Do the Children of the Forest have the right to massacre people with the White Walkers since the land is originally theirs? Can the House Targaryen begin considered Invasors in a already Stolen Land?
Why the Starklings can reclaim Winterfell after their House was usurped but not Daenerys? Because she wasn't raised here her claim is not valid? Her brother Viserys was older then Rickon and was raised as the spare heir in Westerosi culture. Is his claim valid?
Some people are genuine like "Daenerys can't fight Ghiscari/Essos slavery because her ancestors around two hundreds years ago were slavers! That would be hypocrite of her!" Excuse me??? Acknowledge the mistakes your ancestors did and don’t let other people do the same is bad now???
Ghiscari has this whole oppressors-turned oppressed-turned-oppressors-again thats reality break that idea that they were some helpless peaceful victims of the Evil Valyrians
Essos's favored 'superior' culture is probally Ghiscari and Ghiscarized Valyrian culture
I wish we see more of slaves hierarchy, they are more Roman/Ottoman than American, we have teachers and translators that are slaves. Could some of them marry? Get their freedom? Own property? Study? Which ones? I think, since Ghiscari sell even their own people but still consider themselves superior, that Ghiscari-looking slaves are more expensive and more 'domestic' slaves while like...Dothraki or Naath are more towards hard work and sexual slavery? Makes sense history-wise
I watched Magnificent Century, Ibrahim and Hurrem begin both slaves while begin a beloved childhood friend and wife to the Sultan were such complex relationships
