You know one tactic is to ask for more unsullied in other regions like Pentos (1500) and Volantis (maybe 4000) or even Lorath (500), I don't think there are as many as in Astapor but it would give it more numbers and prevent Lys, Tyrosh and Myr from killing them. bought later in the middle of the war. Another would be to hire the Rose Company are Northerners and it is the strongest Company before the Golden Company could besiege Myr and conquer it.
Hi Just a suggestion you should try and give Corlys a new Valyrian steel sword to improve relations with him and it would help to have the most successful sailor and adventure on your side. With his help you could start a large trading company and get rich quick. Also with the help of MC's fire magic he could the worlds larges salt trade since all the has to do is create a large salt factory in dragonstone using the volcano to boil water till salt is formed and the stepstones with the help of his fire magic. Since salt is considered a hug cash resource since it requries a hug amount time and energy to make or the would have to find a mine, which makes it expensive. By selling it in large quanties and getting his own set of merchants he could make a lot of money.
Sou meio tendencioso quando se trata do Norte, se tu ajudar os Starks acho que solidificaria a aliança, se não me engano o Norte nunca perdeu uma guerra. A linhagem dos Starks remonta à 10.000 anos. Nem os Valirianos são tão antigos. A culpa dos nortenhos passarem problemas por conta da comida, é culpa dos Targeryen que deram as terras férteis a patrulha da noite. Eu gostaria te ver uma filha do MC como senhora de Winterfell. Afinal, o Norte se lembra. Faz o MC criar uma armadura de aço Valiriano. E se possível, dá uma descrição do estandarte e as palavras da casa.
