If you rarely get to visit Disney parks, then you might naturally want to make park time a higher priority. If you visit often, I think Disney Springs is a great way to expand your Disney experience. Then again, I like touring the various resorts as well and enjoying the Disney theming -- which is not everyone's idea of fun.
Another factor: it's exciting to try a variety of dining at WDW, and Disney Springs has a lot of great options. Also, I'm not a big shopping mall person in my day-to-day life, so when I'm on vacation I don't mind visiting some stores and getting myself a pair of shoes or a new shirt that doesn't necessarily have Mickey Mouse printed all over it.
Also, Disney Springs is best during those times when the parks aren't open as late, especially if you don't feel like hopping (or don't have hoppers). I enjoy grabbing a beer and listening to the bands play.
