Winter map
I'm pretty new to league, so I'm not sure if they do this every year. Recently I was playing, and everything was fine. Then I load into a new game and BAM the map looks all cold and wintery. Now at first it looked kind of cool, but eventually it started to hurt my eyes. Not like, "too bright" hurt my eyes, but for some reason the contrast between the creeps and the background feels really off. It's really hard to concentrate for me because of this.
Is there any way I can disable it? Since it makes no gameplay changes is there any reason I shouldn't be able to turn it off?
If there is no way to do it, how long should I wait? When is it expected to be removed?
