I am all for Wynn Dorson taking Daala's place. He would make a good fit as he seems to be pro jedi allthouth he is a bit more coniving than her at least in this series fotj. Some of the long term plotting she has displayed in other novels (a more long term approach) seems to have been lost in this series. She is being written as being very single minded towards her disbanding of the Jedi Order and has lost her ability to take a more long term approach to the issue. As far as Ben and Luke are concerned I the the authors are doing an excelent job of showing the concern for one anothers safety as well as their trust in each others abilities especially Luke's trust in Ben. Something tells me Ben will be the key to the defeat of Abeloth and will end up being Knighted after this series.
