Are the Dothraki even mentioned anymore? Aren't there like thousands of them?
Assassin:
I think that the lady preacher in that city that Tyrion was kidnapped in was saying that the fire church has picked their new leader and it is Daenerys - aka not Stannis - hints that Melisandre will potentially betray Stannis. I think that Jon Snow will default into control of Stannis' forces, because it's boring to have him just hanging out with the Night's Watch. Brienne will probably kill Stannis, but Melisandre will potentially default to Team Dragon.
Arya will kill Walder Frey just to build her up, then she will go after Cerci who will be defended by the Mountain, then she will kill him and 1v1 Cerci. I don't know how that fight will end, but it's pretty convenient that Arya's whole list are just Cerci's underlings.
Little Finger will have a bunch of houses out of nowhere, but Cerci will get p---ed at him and try to murder him out of nowhere.
Daenarys will have a bunch of scenes hanging out with Tyrion and Varys, then after one of the other three is knocked off, she will attack. Bran Stark will Worg power her dragons and turn the tide. A random character will want her dead.
