The Skywalker lineage and Luke's wife have been in the EU for quite some time now. What was your reaction when Disney announced that the Legends cannon would exist unto itself, and that long familiar characters (notably the three in the OP) would not be involved in the upcoming films? Did these characters contribute heavily to Luke's development in your opinion, or do you think that it was best for future cannonical films to start anew? Did you find Jacen and Jaina's birth/development to be nothing more than a rehash of Luke/Leia's?
