LB,
Without wanting to sound insensitive, if you've been fortunate enough to manage to not start WoT yet (unlike us unfortunate sods who've been waiting 12+ years for it to finish depending on when one started reading it), at this point it is probably worth waiting to see if RJ actually finishes the story first. RJ has said there is only one more book to go even if book 12 is so big you have to carry it home in a wheel barrow, BUT he is, as you're probably aware, very sick at the moment.
Like all WoT fans I wish RJ the best and my prayers are with him and his family, but I have to question why you would start a series that may never be finished if you can avoid it? If RJ pulls through and finishes the story then by all means go ahead and read it. The first 6 books were, IMHO, some of the best fantasy ever written (although obviously not everyone feels that way), and if the last book is as strong as the 11th, then hey, 7 out of 12 aint bad!
