Just saw this thread and have to put my two cents in. I absolutely love the series. This is actually the reason the reason I got into rping, albeit accidentally.
I'll go ahead and answer the questions posed at the start for now.
Favorite book? Hmm.. Lord of Chaos, simply because of Dumai's Wells. Then again, the One Power was one of my favorite aspects. Especially the fighting weaves.
For a heart touching moment, there is a bit of a spoiler here.
When all the characters were dying at the end and Rand was watching them, helpless.
Mat is likely my favorite character aside from Rand himself. He has that carefree attitude, yet always manages to do the right thing. Plus, his jokes had me laughing many a time.
And this one is probably the most common one, Winter's Heart. It just dragged
on and on it seemed.
On another note, if someone would be interested in rping WoT, feel free to message me. Even if you just want to talk about the books or whatever you can PM as well.
