I just got the Quest to Collect 10 Sigils of Power and 10 Sigils of Wisdom from the Black Prince. Wondering if I can do LFR to get these items or if I need to do normal version of the raids to get them.
UPDATE: 11/5/2012 (Patch 5.0)
I have been doing Mogu'shan Vaults on LFR, and it seems that Mogu'shan Vaults only drops Sigils of Power. My guess is that the other raids will drop drop the Sigils of Wisdom. I will know more on Tuesday when Heart of Fear Part 1 is open for LFR
