There's no need for Lightroom either, but it's nice to have.
And Photoshop "Levels" would have no place in Lightroom...Levels is designed to work on gamma encded images, LR is designed to work on raw images which have a completely different levels distribution (think linear).
LR is designed to be a workflow application for use on raw images. It ain't Photoshop...thank goodness!
ACR and LR work on raw (linear) images, but the readouts and controls work in terms of a gamma encoded space, and the user is not really aware that he is working in a linear space. The levels in Photoshop is a relatively crude tool that allows setting of the black and white point, while the midpoint control adjusts the midtones. This is similar to the Blacks, Brightness, and Exposure controls in ACR or LR Process 2010, and these latter controls work well with linear files. The Process 2012 controls allow finer adjustment of the tonal range.
