Wilderness background is something I would like to see pulled out of druid, and ranger. I want to see urban rangers and urban druids too in the base game. I can envision many rangers who don't have to be the uber-woodsy guy. My vision of a ranger is likely different than most though. I like the ranger to be the smart and knowledgeable warrior. He knows stuff and can put it to use in combat. He knows the terrain, he knows the monster, he knows its weaknesses, heck he might even know a few spells. So I think of them as highly skilled and use those skills to their advantage, often this means knowing the environment, tracking, and woodland like stuff, but it could also easily encapsulate an urban environment, investigation and searching for clues, and city stuff. So open them up to more than a woodsy background.
