World Of Warcraft: BC Question #28: Secondary Professions

Are there master levels of the secondary professions cooking, fishing, and first aid?

Yes, there is definitely another level of First Aid. For horde that is trainable in Falcon's Crest. I haven't found the new levels of Cooking and Fishing yet, but I assume those are around as well. There is a "Chef Extraordinarie" who gives you a few recipes at the "Zeppelin Crash" in Hellfire Peninsula and I've seen links of a few fish I've never heard of before.
