This season hasn't had that much of a conflict yet. Sansa and Jon have been doing their thing, Arya's moving in circles, etc. No conflict has lasted more than one episode, besides Daenerys's (which has been without the rest of her crew) and the King's Landing politicians verses Sparrow one. Even Littlefinger (who's the best) has just been politicking in circles.
Basically, GoT needs more friggin' conflict.
