i have a dk 68 that works as my "peon" for pots and glyphs, and the reason that i level him to 68 is that it was required to aquired grand master as it was told me on wowwiki.
now with illustrious what is the required level to achive it ? or since you can learn it in orgrimar does not have a level requirement?(my recollection from beta)
