No need of root for theming? well, it's good. But the purpose in rooting a phone is to have total access and control of all of it, themes included. I think rooting to access and modify /etc/hosts file to block ads sites and access to sites without using an external dns server. Other purposes are being able to acess to terminal and run bash scripts. And many others purposes.
