I think while there were a few, my favorite amusing scene is Rand and Elayne, Min and Aviendha expressing their love for each other in front of Lan and Nynaeve
2. What was the best story arc in the series?
Other than the overall journey of Rand, I really enjoyed the Great Hunt story arc.
3. Which character do you think was the most overrated by other characters?
Many of the forsaken it felt, didn't quite live up to people's fears for the most part.
4. What were the best and worst parts of Sanderson's writing?
Finishing the story off was the best part, potentially helping speed things along though I felt Jordan in his last book was already achieving this, for worst parts, he just seemed to not get a lot of the world, and Androl seemed a bit too Mary Sueish.
5. Which culture was your favourite and why?
Hmmm, tricky one, probably the borderlanders, culture built around trying to protect the rest of the world from the blight.
6. How is it possible there were so many Black sisters? I read somewhere that it was roughly 200 persons, making the Black ajah almost as large as the Red.
Can't help you there - I have trouble following the overall numbers, when they seemed to suggest quite short of 1000 sisters all up, the numbers lost along the way, seemed to suggest there shouldn't have been as many as there were at the Last Battle, and given how many lost there, not many at all after outside of all the new recruits.
7. How do you see the future of Randland unfolding from now on (e.g. Seanchan, Aiel, Asha'man, Kin)?
Not sure, depends on how well the Dragon's Peace holds - I think with the Aiel acting as police then Aviendha's vision won't come true, but otherwise I can see things settling down, with the Aiel integrating into the main populace and the Seanchan losing compulsory Damane, but keeping voluntary ones, and the other nations staying stable.
