I'm a 450 Grand Master engineer, and until this last patch I could use the Engineering AH even though my professions were all messed up and called me a Master with 450 skill. Now that I'm properly a Grand Master again, however, I can't use the Dalaran AH - it tells me I need to be a Grand Master. XD
