Here is a list of summarized topics of all "highly rated" posts in the thread where Blizzard wanted our questions about professions, in order by first submission.
-- T12 flasks
-- unobtainable old-world recipes
-- lack of RP in archaeology (you just sell the greys)
-- dailies for other professions
-- new flying carpet
-- BoP crafting recipes dropped in raids
-- crafted wands
-- some kind of error message when you miss a skillup because you forgot to train the next level range
-- fun craftables
-- lower material costs of dreamcloth
**editor's note: the asker pointed out, correctly, that the mats to make dreamcloth cost more than the dreamcloth itself. This is to be expected. Ingredients almost always cost more than the final result, because ingredients have potential to be many things, and the completed item does not.
-- T12 goggles
-- orbs becoming BoE/BoA
-- glyph books in Cata
** This was the number one most posted question, by the way
-- crafted mounts for other professions
-- skinning gives no exp
-- neither does fishing
**editor's note: nor should it. You can sit and chain-fish in a safe zone indefinitely.
-- archaeology is boring
-- so is fishing
-- equal treatment for professions in terms of recipes dropping in T12 content
-- explaination of the Working Overtime bonus
-- the speed of levelling up gathering materials at low levels
-- why do JCs have the most recipes and learn them the slowest
-- removal of slot requirements for enchanting
-- the mats required for 346 weapons
-- the highly limited drop zones of Arthas' Tears, Felcloth and Ghost Mushrooms
-- archaeology puzzle minigame
-- epic recipes for casuals (i.e. BoE drops)
-- epic or orb-using JC BoE's
-- there aren't enough things to do with inscription
-- more archaeology sites per continent at higher skill levels
-- recipes that require more than one profession to complete
-- engineers need more gear to make
-- more Tolvir sites
-- blacksmithing specialization (come back! please!)
-- multi-stage upgradable crafteds like the BC crafted weapons/armor
-- archaeology drops for rogues (other than the axe)
-- Cata-versions of the crazy alchemist or endless mana potions
-- RNG RNG RNG archaeology
-- new tier of materials in 4.2
-- recipes from epic questlines
-- tutoring for first-time players learning professions
-- more archaeology races
-- the names of the tiers of profession skills ("illustrious Grand Master") suck
-- epic gems
-- archaeology in Outlands doesn't have enough rares
-- gathering nodes in phased areas
-- more total glyphs
-- choosing the secondary stats in crafted items
-- some kind of compensation for LFD disenchanters, such as the ability to use and keep the extras from the guild perk, or else an on/off switch
-- transmute cooldowns linked
-- a Cata fishing tournament
**editor's note: that isn't a complete RNG lottery waste of time like the Dalaran one
-- the top hat (and monacle combo)
-- fishing boat mounts
-- first aid is useless at higher levels. it needs more powers (CPR) or items (anti-venoms)
-- scrapping items for crafting materials and greys
-- Cata-level fishing dailies with better prizes
-- hoverboards
-- guild challenges based on professions
**editor's note: most professions are solo work. Guild challenges require group work. These wouldn't be easy to make.
-- there is no use for nexus crystals
-- let us catch critters and tame them as pets
-- revisit the need/greed rolling system on BoE recipes, glyph books, and materials that drop
-- why do engineers have to explode
-- didn't you promise to overhaul fishing in 2009?
-- converting the +1 cooking/+1 fishing from dailies at max skill to gold
-- titles earned by professions
-- better filtering in the crafting menu
Edit: I have highlit in blue the questions that were asked enough times by enough people to warrant an answer, even if the answer is "no".
