There are very few that I would put on that list and even those could be fine depending on your intended use and the price you pay for them. For example, a lens that's a bit soft in the corners could be fine (or even desirable) if you were using it for portrait shots. A better way to get information on this is to identify a specific lens and talk about what you plan to photograph with it and what you plan to do with the images. If you then add your budgetary plans or other constraints, that helps us all answer the question as best we can.
A good example in my case is the newer 24-85mm VR lens. It's not the sharpest lens I own and you could say that it doesn't take full advantage of the D800e's sensor, but it's very small, lightweight, and it has a nice range for family shots. It also has VR. Having it attached to my D800e is a completely different experience than using my 24-70mm. For casual use, it's great. It's not what I would use if I were selling 24x36 inch prints of landscape images, but that's okay.
