The test realms haven't actually come back up yet so I'm unfortunately unable to get a list of recipes that have changed, but it sounds like leveling Cooking will suck much less. I think my it took my Priest longer to hit 450 Cooking than it took my Paladin to hit 450 Blacksmithing. After grinding through that, I never want to make another Feast again. Unfortunately, I'm sure I'll be making them by the dozen when Ulduar rolls around. Sigh.
I would do a great many things to be able to summon Jillian on demand.
