I like the spy. So I will throw my support behind her here, I suppose. First, she starts with plenty of stuff. On the poorer side, but that cigarette case will come in handy when you make the wrong choice with your sliders. Second, with Breaking the Limits, she has the highest stats in the game bar none, so if you need to, you can really wreak some havoc. If she bumps them all the way up, for instance, 4/4 fight/will, with six sneak and 5 lore. This could go with 3 speed/2 luck (at the cost of 3 sanity/stamina) so she could sneak some troublesome monsters, then assassinate something she's equipped to deal with (perhaps with a spell). I can see her as a really good spellcaster, if she comes across some. Especially with the expansions, spells can shore up many slider issues anyway. Sure, if she's a spellcaster she'll have issues with Breaking the Limits, but I think that's a fine cost for such amazing flexibility. I mean, just the ability to have her fight and will both at max puts her on relatively even footing with the best fighters. I definitely applaud the bold choice, and I think they handled it fine (play pending). She's definitely not for beginners, at any rate. I can't wait to see what she can do.
As far as the chef goes, I think I like her too. Mechanics aside (and they are good), even knife-wielding maniacs would have some stake in keeping the world around. As long as they aren't disciples of Azathoth, I mean. If you belong to a group of roleplayers, doesn't at least one of you want the chance to play that?
