There are numerous problems with this series, but I do think that no answers is not one of them. Instead I'd argue that the sense of missing information comes from the gaping plot holes. there are just so many things that simply don't make sense but it isn't because of a lack of information. Confession: I skimmed the last third of the novel, because it bored me. Also I'm of the opinion that death is a salt, use to much of it in your novel and the novel suffers. Thats been a huge flaw in the series from the beginning. One, two deaths has meaning, more then that and you risk numbing your reader. Consider me numbed.
