I sold 3 noble cards for a total of 14k gold, cost me about 800g in mats to make them too (and got a bunch of other cards too but they didn't sell as well).

Tailoring is just a mediocore a profession imo unless your team is all clothies, and there really isn't much thats BOP anyways (woot a flying carpet! and a slightly cheaper-to-make leg enchant).

Inscription is currently one of the worst profs in WOTLK, but I would guess blizz buffs it up in a future patch pretty majorly -- after all, Jewelcrafting kinda sucked badly when TBC launched, but now many consider it the best profession in WOTLK. It would not really suprise me to see in patch 3.2 or later for Inscriptors to get an extra major glyph as Blizzard initially wanted to do, it really wouldn't be super OP but give inscriptors a big leg up.
