Crafted food is still better, lasts longer, and doesn't poof in 24 hours. I can understand your concern on the lower level foods though. Even though your swamp mix lasts longer and doesn't poof in 24 hours.

For alchemy it is still a very good craft profession ATM to have because you can a) make a variety of potions that the house maid can't make, b) things don't poof after 24 hours but considering how easy it is to get more that really isn't an issue. The potion buffs also last a very long time too.
As to cooking, yea.. Really All i can say is that cooking got the short end of the stick. Yea food from the house maid is 5min versus 15 min with crafted food. NOT a big deal but yea it's annoying to have to do mid fight (I believe there are addons to manage it for you). Lack of variety I think would be the biggest issue against cooking really atm. With alchemy there are lots.. well there are other potions that are desireable, versus cooking really just a few for any class are really desired. Again the 24 hour duration is really a NON issue, just nuke any of your old stuff you had when you log in, talk to your house maid whamo blamo you have stacks of 100 of said item. Which should be more then enough for a play session and if it isn't ... well not hard to get more.
They cook, they clean, they buff.....but they won't water my plants?
Mine doesn't do windows or heck make the bed!!!!!! Dang lazy maid!!
