Thereare 2 types of magic, good Magic (which some talented people can use) and Vir which is a dark magic that slowly takes over a person making them despotic and crazy; this is "Gifted" by one of the Big Bads of the series
He goes on to describe how many of the common elements in the two series were both based on the same inspiration - whether that be from real-world history, myths and legends, or other fantasy works such as Tolkien's - rather than NA being a ripoff of WoT.
Those guys each have a couple of decades of writing experience on me, so if you think they do it better than I do, that's fine. My work is definitely influenced by them, and it's influenced by Tolkien, and it's influenced by a bunch of other writers both famous and gifted and not-so-much. At the end of the day, I think if you tore off the cover and read any of my books without seeing who wrote it, you wouldn't say "Hmm, seems like a pale Robert Jordan. Maybe something from early in his career?" I think you'd say, "That's a Brent Weeks book. Definitely."
Whether Weeks was telling the truth here, or simply waffling to cover up the fact that he did rip off Jordan, is up for debate. But your question was whether he's talked about it, not whether he copied from WoT.
I found this by searching Google for brent weeks wheel of time, which led me to this forum thread, with a link to this page which no longer exists. It then took me ages, even using the Wayback Machine, to find a copy of that page, but eventually I managed it using this list.
