But Herschel brings age and wisdom to the group.
Yeah, since Dale died I really think Herschel stays and retains that capacity. It was either Dale or Herschel last season, and I think Herschel was the far more compelling character.
And a lot of knowledge: farming, medicine, some mechanical knowledge from working with generators, etc. I find Milton to be an interesting character, but he doesn't have as much to offer as Herschel does.
