The new Rift's 'quadrants'

"We wanted players to be able to glance at the stream, screen or screenshot and know instantly where the camera was based on the surrounding environment," says a Riot post from 4 months ago. The post then goes on to explain how each 'quadrant' of the new Rift has a different sort of theme, so that players will be able to tell where they are on the map based on the theme of that area. What the hell? Like, after you've played maybe 5 games of League you can tell exactly where you are in a split second based on the map. And even if you haven't, it's not like you'll instantly memorize which quadrant has which color scheme. I really don't understand why they did this...
