Eh, they're still nice *as furniture*, just not as crafting stations. ;My alchemist has a simple table in her room, just to say "hi, I'm a level 70 alchemist".
I'm planning to leave the crude and pristine for sale but remove the middle ones from the merchant.; That way people can still buy a cheap one as furniture, if they want.; (Pre-existing intermediate quality stations will of course remain in the game, they just won't be selling new ones.)
