The other issue is that this may destroy the fishing economy -- if even low level characters always get the fish they want 100% of the time, that means more fish in the market, which means any money high-level fishermen would have made off of rare fish will probably go bye-bye. But Wryxian says that's OK -- people will still use fish for themselves, and he believes that the pain of losing that AH sale will be solved by the bonus of always getting the fish you want. We'll have to see -- it's true that between the updates to cooking lately (and the future fishy updates we're expecting), Blizzard is making sure the secondary professions are much less exclusive, which means there has to be the balance of also making them less lucrative.
