There is a whole profession income ruined to hell.
Prices for a top elixirs discounted by 75-85%
Before this, typical hunter had to farm 15g for a stack of Mongoose. Killing mobs or sell things on AH or selling boosts, whatever.
Now all he need is just to sell some gray crap, because Mongooses stack costs 2.5g on Auction House.
