[Spoilers Published] GRRM should have gone on a massacre in AFFC and ADWD

The reason why I believe WoW is delaying to come out is because both AFFC and ADWD left more questions than answers. There are two many plots, no significant resolutions and too many questions with no answers. This could have been prevented if GRRM had gone on a massacre in the previous two books.

AFFC and ADWD would have made more sense if GRRM had dedicated these two books to tying loose ends. He should have been ruthless in exterminating any character that wasn't key to the Westeros plot. Many characters should have been dropping down like flies in these two books. It should have been a blood bath. Every subplot like the Dornish plot, Northern Conspiracy should have significantly advanced or at most had a resolution in those two books paving the way for WoW.

From what I see, WoW is supposed to be the books where the Starks, Lannisters (Tyrion) and Targaryen (Daenerys) get to converge in Westeros for the final confrontation before the Long Night begins. This was the essence of that book. It would have simply wrapped up all unanswered questions from the two books and prepared the world for the winter. The real massacre should have occurred in the previous two books.

Except he intends to split WoW in two, I doubt that he will able to answer all questions in that one book.
