What if some of the rewards for beating group missions and/or raid missions in the new expansion unlocks slightly different looking terrain. Make it progressive group progression does some and raid content does others. The infected ice going away or thawing a bit. I know ALOT of people are a little tired of BLUE WHITE landscape. Seeing some other colors out there would be amazing. It would feel like you REALLY have an effect on the game. Thoughts? Doggie bag?
