Implementation of season to summoners rift

Just like the implementation of a snowy summoners rift with which you could play in even during ranked games I believe riot should do this throughout the seasons. I especially enjoyed the change to the rift and played ranked all the way through the snowdown changes. A fall texture would look very good as well a summer or spring texture with flowers or a dried out river. Of course these could be disabled in the menu but I for one enjoy the changes to the rift in terms of background.
