If you view the Merneese situation as a matter of choices then the story is not so bad, the story is how Dany has to suffer she can not have everything, she may have magic but she is no god or Mary sue. If she wants to be a messaniac figure she will pay for it with lots of blood, nor can she be a sansa or child dany for in that path she will be a pawn and events will still happen just around her not through her.

She must move, she must sacrifice the only question is what will be her blood price what will she pick as the toll.
