Aww crap. Here's to hoping they change it.
I just went through tailoring and ran into the same problem. You can get to like 565 or something and run out of recipes. When I visit the trainer in the silken fields, I can't interact with him other than a simple message he gives. But he does have a greyed out exclamation point (at 85) for a potential quest, which is the questline I'm assuming will open him up with hopefully more stuff to train.
I sure hope they don't gate the professions with level requirements like they did in Cata (but even in Cata it was only some professions)
