Here's my outline of a plan from one of the LOTF discussion threads, although I was talking in the context of a rewrite, which I'm still planning to do in this upcoming year:
1. Internal consistency with numbers and political alignments (the Imperial Remnant is part of the GA in Betrayal, with Pellaeon as GA's supreme commander, back to a separate political entity in
Revelation).
2. Make Jacen a compelling villain, and have progressive character development rather than going back and forth. (In other words, if Jacen decides that he is Darth Caedus in one chapter, and thus has no twin sister, don't have him angst about fighting Jaina two chapters later--this actually happens in
Revelation.
3. Write
Star Wars, not a political commentary on current events.
4. Don't kill characters off for shock value; the death must have a purpose, and that purpose must be defined, and must not change from book to book to cover up the fact that the real purpose was, in fact, shock value.
5. Show that there are
some consequences from the Yuuzhang Vong war.
6. No revisionist bullshit. Boba Fett hasn't killed "more Jedi than anyone", he hasn't killed any. He was thrown in the Sarlacc by a barely trained Jedi and a blind man.
7. Yes, we all seen the prequels. No gratuitous references to prequel events and locations, especially if the characters shouldn't know about them. If you make references, at least make them correctly. (Note to KT: Qui-Gon Jinn did not kill Darth Maul).
8. 54-year old women usually don't get pregnant. That goes double if they're married to 71-year old men.
9. *Group X has been in hiding from everyone, and no one knew about them, but they show up when it's convenient for the plot*. It was
slightly compelling when Zahn did it with Thrawn. Then we had Palpatine's clones, Daala, Eye of Palpatine, Hand of Thrawn, the Shadow Academy, the Vong, Mandalorians, Kiliks, Lumiya, the Sith on Korriban, and now Daala again. There's a reason
deus ex machina is considered a bad plot device.
10. No SoD-killing references to fandom (i.e. characters talking about Han "shooting first").
11. Competence on both sides. Jacen should have been killed a long time ago, but was saved by Luke's, Mara's, and Boba Fett's stupidity.
12. Consistent character spectrum. A quarter of the first book about X-wing pilots, a quarter of the second about Fett, a quarter of the third about Saba, Zekk, and the Hapans, then going through the cycle again is another of those things that kills SoD. Even the NJO, at least in the later half, wasn't that jarring.
Now that the series is over, we can add:
13. No Mandos. Self-explanatory.
14. The Joiner crap was a hallucination on the part of Jaina, Zekk, and other Jedi who overdosed on illicit drugs and needed Force-induced therapy to return them to a state approaching sanity.
15. Have what happens logically lay the seeds of
Legacy.
16. For Force's sake, one way or another, resolve the Jaina/Jag/Zekk triangle. And no, Zekk being MIA is not the way to do it.
17. Do not create potential for Allana to be Luke Skywalker 2.0.
