I think Elayne gaining the throne of Andor can be cut down quite a bit too. It stretches across four books as far as I can remember and although some interesting bits it could be made leaner.
I agree Ivien. I think some books could be a full season but otherwise would have to be mushed together. I hope they don't try to make 10 seasons, it's just too much and shows tend to get tired after too many.
