I couldn't find the original thread where this was discussed. It was implemented without being announced, but I noticed it and complemented the change at the time. A while ago, when a raid was running, the wallpaper on the home page changed to a raid boss theme from the standard one you see with similar images on the main site. I don't recall for sure, but I think it was the Arsonist, and the artwork was really neat. It really stood out from looking at the same thing every day. I know it doesn't add anything to the game, but it's a good idea to change things up every once in a while. Since the artists don't do anything else dev-related to the games, why can't they change the home page backgrounds for a few days once a month? They don't have to be raid-related, maybe they can be holiday-themed like some of the calenders are, or different boss images?
